Pulls the canonical 11-category list and the pure stats math out of
internal/handlers/ so the upcoming JSON API can reuse them without dragging
HTML rendering along.

- internal/categories: Label/Slug pairs, All() accessor returning a copy.
- internal/insights: Month()/Year() compute totals, category rollups, daily/
  monthly chart series, percent-change, MTD comparison, and average-per-day,
  taking a *storage.DB and a now clock; no HTML, no http.ResponseWriter.
Introduces internal/api/ — a JSON HTTP layer the React PWA will consume:
- json.go: writeJSON / decodeJSON / error envelope
- auth.go: POST /api/auth/login, /logout, GET /me (JSON over cookies)
- categories.go: GET /api/categories
- expenses.go: cursor-paginated list, create, patch, delete
- insights.go: GET /api/insights?view=month|year
- router.go + middleware.go: wires routes, applies session auth

Adds storage.ListExpensesBefore (composite (date,id) cursor) and
InsertExpense (returns the persisted row with its id). Adds
internal/auth/sessions.go with the SessionCookieName, SessionDuration,
context key, and cookie helpers. Each endpoint has table-driven tests
covering happy paths and error cases.

Remove internal/handlers/, web/templates/, and the legacy vanilla-JS/CSS
assets (datepicker.js, pull-to-refresh.js, style.css, sw.js,
manifest.json) now that the JSON API + SPA fallback are wired up.
cmd/server/main.go was already free of references to these. Dockerfile
copies and the e2e Playwright DOM selectors are intentionally deferred
to Tasks 11 and 13.

Adds web/app/ Vite project that builds into web/dist/ for the Go embed,
with dev proxy to the Go API and vite-plugin-pwa configured for the
expected Workbox runtime caching shape.

Task 6 of the React PWA redesign: scaffold the frontend foundation that
the upcoming components and screens will build on.

- theme.ts: ports the Linen & Ink palette from mockups/v2-clay.jsx as the
  only theme.
- types.ts: Expense, Category, Insights, User, plus list/page wrappers.
- api/client.ts: fetch wrapper with cookie credentials, JSON envelopes,
  and automatic 401 -> /login redirect.
- api/{auth,categories,expenses,insights}.ts: typed request functions.
- hooks/{useCategories,useExpenses,useInsights}.ts: TanStack Query
  wrappers; useExpenses is useInfiniteQuery with cursor pagination.

Add CategoryGlyph, Hero, DayGroup, ExpenseRow, CategoryPicker, Keypad,
CalendarGrid, DatePickerPill, and TabBar under web/app/src/components/.
Introduce a small fmtEUR/splitInt helper module. Components consume the
existing theme + useCategories() hook and use category slugs to drive
glyphs and tones while exposing label-based props to align with the API.
Wires up the React PWA with React Router and React Query:
- Login posts to /api/auth/login and redirects to /
- Feed renders the Hero card and day-grouped expenses with
  IntersectionObserver-driven infinite scroll
- Insights renders the spent/per-day cards, the 31-day bar chart, and the
  by-category list, with month navigation via prev/next arrows
- EntryForm handles both /add and /edit/:id, reusing CategoryPicker,
  Keypad, and DatePickerPill; create/update/delete mutations invalidate
  expenses + insights queries (offline queue arrives in Task 9)
- App.tsx provides QueryClientProvider + BrowserRouter; index.css
  resets to the linen background and DM Sans
Introduces an offline-first mutation layer for expense writes. New
`web/app/src/offline/` module wraps `idb` with two stores: `queued_writes`
(operation log persisted across reloads) and `cached_expenses` (last-N
mirror for offline reads). `useCreateExpense`, `useUpdateExpense`, and
`useDeleteExpense` apply optimistic React Query updates, persist the
intent to IndexedDB, then attempt the network call — network failures
leave the queue entry for replay; API errors roll back the optimistic
update and drop the entry. `setupOnlineSync` in `App.tsx` drains the
queue on the `online` event and once on mount.

…binary

Splits the image build into a node:20-alpine web-builder stage that runs
`npm ci && npm run build`, a golang:1.25-alpine go-builder stage that copies
the freshly built bundle into web/dist for `//go:embed all:dist`, and a
slim alpine:latest runtime that only carries the static binary. Also
adds web/app/node_modules and web/dist to .dockerignore so host artifacts
don't override what each stage produces.

- Add Set up Node + npm ci + tsc --noEmit + npm run build steps so
  go test ./... runs against a real web/dist/ bundle.
- Trim the Go test step to ./cmd/... ./internal/... so we don't try to
  drive the Playwright e2e suite (which still targets the old HTMX DOM)
  and so go list doesn't pick up stray .go files inside node_modules.
- Add a gated Run E2E Tests step alongside Install Playwright (both
  if: false) so the suite is easy to re-enable once selectors are
  updated for the React PWA.

Drop the HTMX badges/tagline and document the new architecture: React +
Vite + TypeScript PWA frontend embedded in a slim Go JSON API. Adds
Offline-first / Installable PWA / Linen & Ink design feature lines, a
Local development two-terminal flow, a Production build subsection, and
refreshes the project structure + tech stack to point at web/app/,
web/dist/, internal/api/, internal/insights/, internal/categories/.
Flags that the Playwright e2e suite needs selector updates for the new
React DOM.

Run the full Task 15 validation matrix and adjust the golangci-lint
config so it stays clean under the CI-pinned v2.7.2:

- exclude web/app/node_modules from lint paths (an npm package ships
  its own Go file at flatted/golang/pkg/flatted/ that has nothing to
  do with this repo)
- exclude revive's "var-naming: avoid meaningless package names" since
  internal/api is the conventional name for an API package

Tests, typecheck, frontend build, and Go build all pass. The two
remaining manual checkboxes (docker-compose data persistence and
end-to-end smoke flows) are flagged as deferred to manual QA in the
plan.
- Backend now accepts both RFC3339 and YYYY-MM-DD dates so the PWA's
  date-picker payload no longer 400s on every create/update.
- Entertainment gets its own slug + glyph + tone so it no longer renders
  identically to Other.
- SPA fallback returns 404 for missing static assets (e.g. stale hashed
  /assets/*.js after a deploy) instead of serving index.html as JS.
- Offline drainQueue distinguishes permanent (4xx) vs transient errors
  so a single bad entry can no longer jam the queue forever.
- Optimistic mutations now roll back the React Query cache when
  enqueueWrite throws (e.g. IndexedDB unavailable / quota / private mode).

- Add GET /api/expenses/{id} so EntryForm can resolve any expense by deep
  link, not just rows in the first 50-item page (previously hung on
  Loading... for older edits).
- Make IndexedDB optional: if enqueueWrite throws (private browsing,
  storage quota), fall back to a network-only mutation instead of
  blocking the write entirely.
