…parency Canvas drawing polish: holding Shift while drawing or resizing a rectangle, ellipse, or diamond snaps the bounding box to a square (square / circle / uniform diamond). Read live off the modifier flags so pressing/releasing Shift mid-gesture updates the shape; lines, arrows, and freehand stay unconstrained. Appearance: a restrained accent picker in Settings > Appearance (System + 7 muted hues), routed through a single Color.appTint token so selection, the active tool, primary actions, and native controls all shift together. System is the default and preserves current behavior. Fix #42: railSurface() now tracks the panel-transparency slider so the left rail and top toolbar recede with the board and the Agent/Settings panels instead of staying fixed and heavy at high transparency. No changes to the protected window composition (PanelController geometry, dock width/gap, rail gutters, toolbar centering) — material/color/gesture only.

Three bundled polish items. All changes are material/color/gesture only — the protected board + dock + toolbar window composition (
PanelControllergeometry, dock width/gap, rail gutters, toolbar centering) is untouched.1. Canvas drawing polish — Shift to constrain
Holding Shift while drawing or resizing snaps rectangle→square, ellipse→circle, diamond→uniform. Read live off the modifier flags so pressing/releasing Shift mid-gesture updates the shape immediately. Lines, arrows, and freehand stay freeform.
constrainsToSquareonCanvasToolandCanvasElementKind(box shapes only).constrained(_:from:event:)helper squares the drag end in the board input view (preview + commit).applyResizesquares the box to its larger side, anchored at the opposite corner.2. Appearance controls — accent tint
A restrained accent picker in Settings ▸ Appearance: System (default, macOS accent) + 7 muted hues.
AccentTintenum and a singleColor.appTinttoken inTheme; allColor.accentColorsites and the twoTheme.Paletteselection fills route through it, so selection, the active tool, primary actions, and native controls shift together.Color.accentColor: on macOS a custom accent only applies under the "Multicolor" system setting, so it can't be overridden reliably at runtime.@AppStorageand apply.tint(...)so the UI re-tints live.3. Fix #42 — side rails follow board transparency
The Settings/Agent panels already shared the board's glass; the fixed surfaces were the floating rails (left action rail + top toolbar).
railSurface()now tracks the transparency slider and recedes on the same curve as the board (kept slightly denser for legibility), so the whole workspace stays consistent as transparency increases.Verification
./script/build_and_run.sh bundlecompiles clean (only pre-existingText +deprecation warnings).Changelog updated under [Unreleased] (Added: Shift-constrain, accent tint; Fixed: #42).
