Remove the app-shell header block (skin label/description/badge). Remove the dashboard-grid wrapper so panels stack directly in main. Add defragProgress prop to StatusPanel for upcoming DOS progress bar. Rename VisualizationBoard title from "Optimize" to "Lo-fi Defragger". Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace the old bordered cards + controls grid + legend grid layout with three compact inline rows (status, legend, controls) matching DOS text-mode aesthetics. Add defragProgress prop and AsciiBar integration for visual defrag progress display. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace HTML range sliders and old transport layout with compact DOS-style rows using AsciiBar components for seek and volume. Remove energy meter, status text, and all legacy transport classes. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Replace card-based playlist items with compact single-line rows using a ">" marker for the active track, inline metadata, and minimal action buttons (Up/Dn/X). Simplify empty state to a single text line. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Replace all modern chrome with flat DOS-blue layout - Solid backgrounds, 1px borders, no gradients/shadows/blur - Grid fills available window height via flex layout - Add AsciiBar tile styles for progress/seek/volume bars - Compact inline rows for status, legend, controls, transport - Flatten skin variables to solid colors - Remove unused getSkin import from App.tsx - Remove all responsive media queries Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Remove props that are no longer used after the layout flattening: - StatusPanel: remove bpmStatus, currentLaneCapacity, currentLaneFill, effectiveBpm, estimatedBpm, rowsCompletedInPass, rowsPerPass, formatSpeedLabel import - TransportPanel: remove analysisEnergy, bpmStatus, currentTrackMissing, isTrackLoaded from interface - App: remove currentLaneFill computation, stop passing removed props Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Switch from CSS grid of div boxes to a <pre> block of colored block characters (█). Each cell is a single monospace glyph with foreground color on the background — just like real DOS text mode. - Zero gaps between cells, no borders, no padding - DOS-accurate colors: white=used, green=reading, yellow=writing, red=bad, gray=unmovable, transparent=unused - Dynamic density: columns and rows computed from viewport and character size, filling nearly the entire window - Legend swatches now use colored █ characters - AsciiBar tiles now use █ (filled) and ░ (empty) characters - Font stack prioritizes DOS-era fonts (Perfect DOS VGA 437, etc.) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

4-8: Consider using a static import for the React plugin.The async
defineConfigwrapper with a dynamicimport()adds complexity. Vite natively supports ESM, so a static import typically suffices:import { defineConfig } from 'vite'; import react from '@vitejs/plugin-react'; export default defineConfig({ plugins: [react()], });If this pattern is required for Electron Forge's Vite plugin to resolve modules correctly, consider adding a brief comment explaining the rationale.

Verify each finding against the current code and only fix it if needed. In `@vite.renderer.config.ts` around lines 4 - 8, The config uses an async defineConfig with a dynamic import of '@vitejs/plugin-react' which is unnecessary; replace the dynamic import by statically importing react and export defineConfig synchronously (update the top-level import to import react from '@vitejs/plugin-react' and return defineConfig({...}) with plugins: [react()]) or, if the dynamic import is required for Electron Forge resolution, keep the current code but add a concise comment above the async defineConfig explaining why a dynamic import is necessary for Electron Forge's Vite plugin resolution; refer to defineConfig and the react plugin import in the change.runtime/checkpoints/LATEST.md (1)
1-14: Consider whether checkpoint files should be committed.These checkpoint files capture local development state (branch head, validation status). While useful for the author's workflow, they may not provide value to other contributors and could clutter repository history.

20-34: React 19 allowsrefas a regular prop;forwardRefis optional.In React 19,
refcan be passed as a regular prop withoutforwardRef. WhileforwardRefstill works, you could simplify the component signature:interface PlaylistPanelProps { ref?: React.Ref<HTMLDivElement>; // ...other props } export function PlaylistPanel({ ref, ...props }: PlaylistPanelProps) { // ... }This is optional since the current implementation is functional.

34-44: Session save is not atomic; crash during write could corrupt data.If the app crashes during
writeFile, the session file could be left in a partial/corrupt state. Consider using atomic write (write to temp file, then rename):Atomic write pattern
+import { rename } from 'node:fs/promises'; +import { randomUUID } from 'node:crypto'; export async function saveSessionState( incomingState: PersistedAppState, ): Promise<void> { const sanitized = sanitizeSession({ ...incomingState, lastSavedAt: new Date().toISOString(), }); const sessionPath = getSessionPath(); + const tempPath = `${sessionPath}.${randomUUID()}.tmp`; await mkdir(path.dirname(sessionPath), { recursive: true }); - await writeFile(sessionPath, JSON.stringify(sanitized, null, 2), 'utf8'); + await writeFile(tempPath, JSON.stringify(sanitized, null, 2), 'utf8'); + await rename(tempPath, sessionPath); }This is a recommended improvement for data integrity.

28-34: Type guard may need updating if new skins are added.The
isSkinIdguard hardcodes the valid skin IDs. If new skins are added to theSkinIdtype, this function must be updated manually.Consider deriving from a constant array to keep them in sync:
const VALID_SKIN_IDS = ['classic-ms', 'crt-lounge', 'studio-modern'] as const; export type SkinId = typeof VALID_SKIN_IDS[number]; function isSkinId(value: unknown): value is SkinId { return VALID_SKIN_IDS.includes(value as SkinId); }This is a minor maintainability suggestion.

276-280: Consider adding error handling for fullscreen toggle.The promise rejection from
toggleFullscreen()would be silently ignored. If the fullscreen API fails, the UI state (isFullscreen) could become inconsistent with the actual window state.🛠️ Suggested improvement

199-205: Consider logging audio playback errors for debugging.The empty catch block silently swallows errors. While
setIsPlaying(false)is the correct fallback behavior, logging the error would help diagnose playback issues.🛠️ Suggested improvement

266-279: Minor: BPM cache entry not cleared when track is removed.When a track is removed, its entry in
bpmCacheRef.currentis retained. For long sessions with many track additions/removals, this could lead to unbounded cache growth. Consider clearing the cache entry.🧹 Suggested improvement

Inline comments:
In `@build-windows.bat`:
- Around line 1-36: The batch script build-windows.bat currently uses LF-only
line endings which can break cmd.exe parsing; convert the file to use CRLF line
endings (Windows-style) so every line (including lines with "call npm ci" and
"call npm run make:win", the IF blocks and the final "exit /b 0") ends with
CRLF; update the repository file encoding or run a tool/IDE (or
dos2unix/unix2dos) to replace LF with CRLF and commit the corrected file.
In `@index.html`:
- Line 2: The HTML root element is missing a lang attribute; update the <html>
tag in index.html (the HTML root element) to include an appropriate language
code (e.g., lang="en") so assistive technologies can detect the document
language and satisfy accessibility requirements.
In `@launch.py`:
- Around line 74-83: The code currently returns the first executable in each
Linux bundle directory (linux_dirs -> directory -> candidates[0]), which can
pick helper binaries; change the resolution to pick the packaged app binary by
name: within the loop over directory, look for an executable whose filename
matches the expected product binary (use PRODUCT_NAME or a configurable packaged
binary name) and return that path (falling back to the existing first-executable
behavior only if no named match is found); update references in this block
(linux_dirs, directory, candidates, PRODUCT_NAME, out_dir) and make the expected
binary name configurable if your packaging emits a different filename.
In `@runtime/checkpoints/context_checkpoint_20260306T114515Z_phase-start.json`:
- Line 4: Remove or anonymize the exposed local filesystem path in checkpoint
metadata: locate where the JSON checkpoint writer emits the "repo_root" field
(see "repo_root" key in context_checkpoint_20260306T114515Z_phase-start.json and
LATEST.json) and change it to either omit the field, set it to a neutral value
(null or ""), or replace it with a standardized relative/anonymized identifier
before serializing; update the checkpoint generation/serialization routine that
populates "repo_root" so all produced files no longer contain developer local
paths.
In `@runtime/checkpoints/context_checkpoint_20260306T114749Z_scaffold-ready.md`:
- Around line 1-31: Delete the generated checkpoint file
context_checkpoint_20260306T114749Z_scaffold-ready.md from the PR (remove it
from the repo or revert the commit that added it), ensure runtime/checkpoints
artifacts are ignored by adding an appropriate ignore pattern for that directory
to .gitignore, and if the directory/files were already committed remove them
from the index (git rm --cached) and commit the change so future checkpoints are
not tracked; target the file name
context_checkpoint_20260306T114749Z_scaffold-ready.md and the
runtime/checkpoints artifact pattern when making these fixes.
In `@runtime/checkpoints/context_checkpoint_20260306T120747Z_post-green.json`:
- Line 4: The checkpoint contains an absolute local path in the JSON key
"repo_root"; replace that value with a relative path or neutral placeholder
(e.g., "." or "<REPO_ROOT>") so personal filesystem information isn't committed,
update the "repo_root" entry in the checkpoint JSON
(context_checkpoint_20260306T120747Z_post-green.json) accordingly, and if these
generated checkpoint files should never contain environment-specific data,
change the generator to emit relative/placeholder values or add the checkpoint
file pattern to .gitignore to avoid future leaks.
In
`@runtime/checkpoints/context_checkpoint_20260306T131254Z_distribution-post-green.json`:
- Around line 1-47: Remove the generated checkpoint artifact (the
context_checkpoint_20260306T131254Z_distribution-post-green.json file) and any
other files under the runtime/checkpoints directory from the PR, add a rule to
ignore runtime/checkpoints/** in .gitignore, and update the commit by running
git rm --cached for those checkpoint files then commit the .gitignore change so
machine-specific/transient JSON checkpoints are not tracked.
In `@runtime/checkpoints/LATEST.json`:
- Line 4: The committed checkpoint file runtime/checkpoints/LATEST.json exposes
an absolute local path in the "repo_root" field; remove or sanitize that value:
either delete the "repo_root" key from LATEST.json, replace it with a relative
path or placeholder (e.g. "." or "<REPO_ROOT>"), or add
runtime/checkpoints/LATEST.json to .gitignore if this file is only for local
resumption, and ensure any code that reads LATEST.json (if any) can handle the
missing/placeholder "repo_root" field (adjust deserialization in the reader if
needed).
In `@src/app/components/AsciiBar.tsx`:
- Around line 3-9: The AsciiBar component API allows rendering a slider/meter
without an accessible name because AsciiBarProps marks label as optional; make
the accessible name required by changing AsciiBarProps to require label (i.e.,
remove the optional flag from label) or alternatively add a required prop like
ariaLabel/ariaLabelledBy and wire it into the rendered input/meter via
aria-label or aria-labelledby; update all usages of AsciiBar (including the
instances noted around lines ~85-86) to pass the new required prop and ensure
the rendered slider/meter elements use that prop for their accessible name.
- Around line 11-17: Sanitize non-finite inputs in clampNormalizedValue and
normalizeTileCount: check Number.isFinite(value) (or isFinite) and default to 0
for clampNormalizedValue and to 1 for normalizeTileCount before applying
Math.min/Math.max/Math.floor, then continue to clamp/round as currently
implemented so NaN/Infinity cannot propagate into aria values or rendering.
In `@src/app/components/TransportPanel.tsx`:
- Around line 96-102: The button's onClick currently discards the promise from
onPlayPause (onClick={() => void onPlayPause()}), which can hide rejections;
update the TransportPanel button handler to properly handle the promise returned
by the onPlayPause prop—either make the handler async and await the call with
try/catch around await onPlayPause(), or call onPlayPause().catch(err => process
the error/log it) so any rejection is handled and doesn't become an unhandled
promise rejection; ensure you reference the onPlayPause prop and the Play/Pause
button's click handler when making the change.
In `@src/app/formatters.ts`:
- Around line 12-15: In formatDuration, don't treat 0 as missing: replace the
truthiness check on totalSeconds with an explicit null check plus the
finite-number guard (e.g., test totalSeconds === null ||
!Number.isFinite(totalSeconds)) so that 0 is considered a valid duration while
still guarding against null/NaN/Infinity; keep the rest of formatDuration logic
intact and use totalSeconds when formatting.
In `@src/electron/library.ts`:
- Around line 20-32: The walkDirectory function can recurse into symlink cycles;
update it to skip symbolic links and/or track visited real paths: check
Dirent.isSymbolicLink() on each entry and skip following those, and add an
optional visited Set<string> parameter (or create one at root) where you resolve
each directory with fs.realpath before recursing and skip recursion if the
realpath is already in visited; reference the walkDirectory function and the
Dirent methods (isDirectory/isSymbolicLink) and use realpath to uniquely
identify directories to prevent infinite recursion.
In `@src/index.css`:
- Around line 19-22: Remove the non-standard CSS declaration "font-smooth:
never" (the property name `font-smooth`) from the rule block where
`text-rendering: optimizeSpeed`, `-webkit-font-smoothing`, and
`-moz-osx-font-smoothing` are set; keep the vendor-prefixed smoothing lines and
do not replace `font-smooth` with any non-standard alternative since browsers
ignore it.
In `@src/shared/session.test.ts`:
- Around line 6-8: The test comparing sanitizeSession(null) to
DEFAULT_SESSION_STATE is fragile because sanitizeSession may set lastSavedAt
dynamically; update the test to either explicitly assert the timestamp behavior
or ignore it: call sanitizeSession(null) and use expect.objectContaining to
match all DEFAULT_SESSION_STATE fields except lastSavedAt (e.g.
expect(result).toEqual(expect.objectContaining({...DEFAULT_SESSION_STATE,
lastSavedAt: expect.any(String)})) or
expect(result).toEqual(expect.objectContaining(DEFAULT_SESSION_STATE)) with a
separate assertion for typeof result.lastSavedAt === 'string' or that it is a
valid ISO date; reference sanitizeSession and DEFAULT_SESSION_STATE when making
the change.

Nitpick comments:
In `@package.json`:
- Around line 47-48: The package.json pins `@typescript-eslint/eslint-plugin` and
`@typescript-eslint/parser` to ^5.62.0; upgrade both to a 6.x compatible version
(e.g., ^6.0.0 or latest 6.x) to get improved type-aware linting and TypeScript
5.x support, then run npm/yarn install to update the lockfile, run the linter
and test suite to catch any rule changes, and if needed adjust ESLint config or
peers (ESLint/TypeScript versions) to satisfy any breaking changes for
`@typescript-eslint/eslint-plugin` and `@typescript-eslint/parser`.
In `@runtime/checkpoints/LATEST.json`:
- Around line 32-163: The LATEST.json currently lists 70+ untracked checkpoint
artifacts (entries like
"runtime/checkpoints/context_checkpoint_YYYYMMDDT*_*.json" and .md) that should
not be committed; remove these checkpoint entries from
runtime/checkpoints/LATEST.json (or revert the file to contain only required app
entries) and add a gitignore rule (e.g. pattern
runtime/checkpoints/context_checkpoint_* ) to .gitignore so future context
checkpoints are ignored; verify files referenced in the diff (e.g.,
runtime/checkpoints/context_checkpoint_20260306T131427Z_pr-blocked-distribution.json
and similar) are not staged/committed before pushing.
In `@runtime/checkpoints/LATEST.md`:
- Around line 1-14: The checkpoint file LATEST.md (and other checkpoint files)
appears to be a local workflow artifact and should either be ignored or
explicitly kept as documentation: decide whether to treat checkpoint files as
non-project artifacts and add the checkpoint directory pattern to .gitignore and
stop tracking the existing file(s) (remove them from the index and commit), or
keep them and move/expand LATEST.md into a documented onboarding/architecture
docs location and add a short note in the README describing its purpose so it’s
intentionally part of the repo.
In `@src/app/App.tsx`:
- Around line 276-280: The onToggleFullscreen handler currently ignores promise
rejections from window.lofiDefragger.toggleFullscreen(), which can leave
isFullscreen out of sync; update the handler (the onToggleFullscreen arrow
function that calls window.lofiDefragger.toggleFullscreen and then
setIsFullscreen) to await or then() the promise and add a .catch() (or try/catch
if using async) to handle failures: only call setIsFullscreen when the promise
resolves successfully, log the error (or surface a user-visible
error/notification), and ensure any fallback state is applied on rejection so
the UI remains consistent with the actual fullscreen state.
In `@src/app/components/PlaylistPanel.tsx`:
- Around line 20-34: The component currently uses forwardRef; update
PlaylistPanel to accept ref as a normal prop per React 19 by adding ref?:
React.Ref<HTMLDivElement> to PlaylistPanelProps, removing forwardRef wrapping,
and changing the export to export function PlaylistPanel(props:
PlaylistPanelProps) (or destructure { ref, ... } in the param) while ensuring
the received ref is attached to the root element inside the function; adjust any
internal references to the previous ref parameter accordingly so PlaylistPanel
and PlaylistPanelProps remain the unique identifiers to locate changes.
In `@src/app/hooks/useAudioPlayer.ts`:
- Around line 199-205: The empty catch swallowing errors should instead log the
playback failure for debugging; update the try/catch around
ensureAnalysisGraph() and audio.play() (in useAudioPlayer) to catch the error
object and log it before calling setIsPlaying(false). Use the existing logging
utility if one exists (or console.error) and include context like "Audio
playback failed" along with the caught error so issues in ensureAnalysisGraph or
audio.play are observable.
- Around line 266-279: In removeTrack, clear the removed track's BPM cache entry
to prevent unbounded growth: after computing nextPlaylist (const nextPlaylist =
removePlaylistItem(...)) delete the entry for trackId from bpmCacheRef.current
(e.g. delete bpmCacheRef.current[trackId] or set to undefined) before updating
state; keep the rest of the replacement-track logic (pendingSeekRef,
pendingAutoplayRef, setCurrentTrackId) unchanged. Ensure bpmCacheRef is
referenced safely (exists) when deleting.
In `@src/app/state/playlist.ts`:
- Around line 75-76: The variable orderedIndexes is created but never used;
remove its declaration and update any references that used orderedIndexes.length
to use playlist.length instead (locate in the same scope where
findTrackIndex(playlist, currentTrackId) and currentIndex are defined). Ensure
no other logic expects orderedIndexes (if it was intended to represent index
order, replace its usage with playlist.map((_t,i)=>i) inline or simply use
playlist.length).
In `@src/electron/sessionStore.ts`:
- Around line 34-44: The saveSessionState function currently writes directly to
the session file (uses getSessionPath, sanitizeSession, mkdir, writeFile) which
can leave a partial file on crash; change it to perform an atomic write:
serialize sanitized state to a temp file in the same directory (e.g.,
sessionPath + ".tmp" or use a unique tempfile), fs.writeFile the temp file,
fs.fsync or ensure write is flushed, then fs.rename the temp file over the real
sessionPath so the replace is atomic; ensure mkdir still creates the dir first,
and on any error remove the temp file (or use a well-tested atomic-write
library) so you don’t leave orphaned temp files.
In `@src/index.css`:
- Line 15: Remove the unnecessary quotes in the font-family declaration: keep
quotes only around "Perfect DOS VGA 437" (it contains spaces) and remove the
quotes around Fixedsys, Terminal, and Consolas so the line reads the same fonts
but without extraneous quotes; update the font-family property accordingly.
In `@src/shared/session.ts`:
- Around line 28-34: Replace the hardcoded checks in isSkinId with a single
source of truth: declare a const tuple (e.g., VALID_SKIN_IDS) containing the
allowed skin id strings, derive the SkinId type from that tuple (export type
SkinId = typeof VALID_SKIN_IDS[number]), and update isSkinId to return
VALID_SKIN_IDS.includes(value as SkinId); this keeps SkinId and the runtime
guard in sync and avoids manual updates when adding skins.
In `@vite.renderer.config.ts`:
- Around line 4-8: The config uses an async defineConfig with a dynamic import
of '@vitejs/plugin-react' which is unnecessary; replace the dynamic import by
statically importing react and export defineConfig synchronously (update the
top-level import to import react from '@vitejs/plugin-react' and return
defineConfig({...}) with plugins: [react()]) or, if the dynamic import is
required for Electron Forge resolution, keep the current code but add a concise
comment above the async defineConfig explaining why a dynamic import is
necessary for Electron Forge's Vite plugin resolution; refer to defineConfig and
the react plugin import in the change.

Fallback to a playable track when the current selection is missing.
currentTrackIdRef.current ?? ... only falls back on null. After handleAudioError marks the current track missing, pressing play returns early even if the playlist still has playable tracks. Resolve the current ID only when that track is playable; otherwise jump to the first available track.

Pick the successor before removing the active track.
Once trackId has been removed from nextPlaylist, findNextPlayableTrackId(nextPlaylist, trackId, 'all') can no longer find its position and falls back to index 0. Deleting the current song from the middle of the queue will therefore jump to the first playable track instead of the next one.

Carry autoplay state when file import switches tracks.
Changing currentTrackId on a playing <audio> element loads a new source and pauses the old one. Because pendingAutoplayRef is not updated here, importing files while music is already playing selects the imported track but leaves it paused.

Stop reapplying the startup seek position.
This effect rewrites pendingSeekRef every time the user comes back to initialSession.currentTrackId, so reloading that track later jumps to the stale startup offset instead of the requested position. The ref is already seeded during initialization, so this block is redundant and harmful.

Cap metadata parsing fan-out during imports.
This starts one parseFile per track at once from the Electron process. A large folder import can easily flood I/O and file descriptors, which will stall or fail the import path. A small concurrency limit, or even a simple sequential loop, is safer here.

Reset selection and seek when hydration invalidates the saved track.
After hydration, this only checks whether the saved ID still exists. If that track is now missing, the app restores a dead selection and can carry that stale playbackPosition onto a different fallback track later. Keep the saved ID only when the hydrated track is playable, and zero the position when the selected track changes.

Serialize session saves before reusing session.json.tmp.
Every call writes through the same temp file. If two saves overlap, one call can truncate, rename, or unlink the other call’s temp file, so you can lose the newest state or fail with ENOENT. This write path needs a module-scoped queue or mutex so only one save runs at a time.

Handle non-directory Linux artifacts before calling iterdir().
glob(f"{PRODUCT_NAME}-linux-*") can return files as well as directories. If out/ contains a matching executable file, this loop raises NotADirectoryError on directory.iterdir() and aborts packaged startup.
💡 Proposed fix
if sys.platform.startswith("linux"):
- linux_dirs = sorted(out_dir.glob(f"{PRODUCT_NAME}-linux-*"))
- for directory in linux_dirs:
+ linux_artifacts = sorted(out_dir.glob(f"{PRODUCT_NAME}-linux-*"))
+ for artifact in linux_artifacts:
+ if artifact.is_file() and os.access(artifact, os.X_OK):
+ return [str(artifact)]
+ if not artifact.is_dir():
+ continue
candidates = [
child
- for child in directory.iterdir()
+ for child in artifact.iterdir()
if child.is_file() and os.access(child, os.X_OK)

In `@launch.py` around lines 75 - 81, The loop over linux_dirs can hit
NotADirectoryError because out_dir.glob(f"{PRODUCT_NAME}-linux-*") may return
files; modify the logic that builds/iterates linux_dirs in launch.py to skip
non-directories (e.g., filter using directory.is_dir() or check before calling
directory.iterdir()) so only directories are passed to directory.iterdir();
update the code paths that reference linux_dirs, directory, iterdir,
out_dir.glob, and PRODUCT_NAME accordingly.

--dry-run should not hard-require Node/npm.
The flag is documented as print-only, but this path still exits early on a fresh machine before showing the source-mode commands. Skipping tool validation in dry-run keeps the CLI behavior consistent with its own help text.

In `@launch.py` around lines 117 - 123, The code currently calls
ensure_tool("node") and ensure_tool("npm") unconditionally and may exit on
install_result != 0 even when args.dry_run is set; wrap the tool validation and
the failing-install exit behavior in a dry-run guard so the CLI only enforces
Node/npm on real runs. Concretely, change the logic around ensure_tool,
needs_npm_install, and the install_result != 0 check so both ensure_tool("node")
/ ensure_tool("npm") are executed only if not args.dry_run, and only perform the
exit-on-failure after run_command when not args.dry_run (leave run_command
called with dry_run=args.dry_run so printing behavior remains).

Clear the remaining Stylelint blockers in this stylesheet.
Line 19 still trips value-keyword-case, Lines 391 and 447 do the same with currentColor, and Lines 295 and 452 still violate declaration-empty-line-before. npm run lint will stay red until those are normalized.
Also applies to: 295-295, 381-391, 433-452

In `@src/index.css` around lines 19 - 21, Stylelint is failing value-keyword-case
and declaration-empty-line-before; fix by normalizing keyword case and adjusting
blank lines: convert any CSS keyword values to lowercase (e.g., the
text-rendering value and vendor properties -webkit-font-smoothing and
-moz-osx-font-smoothing should use lowercase keywords, and replace occurrences
of currentColor with lowercase currentcolor), and add/remove an empty line
before the affected declarations to conform to the project's
declaration-empty-line-before rule (update the declaration blocks containing
those properties so spacing matches the rest of the stylesheet).
