Headline:
- Group colour cascades to every non-overridden child (layer or clip
track). New `colorOverridden` flag on Layer / ClipTrack / ScriptTrack
/ TrackGroup; setTrackColor on a non-group pins the track, clearing
re-inherits from the parent group. moveTrackIntoGroup also inherits.
normalizeScene migrates legacy scenes (existing colour ⇒ overridden).
- Keyframes inside a button-asset timeline snap to the 4 state slots
(normal/hover/pressed/disabled). upsertKeyframe / setKeyframeTime /
duplicateKeyframe all enforce it; colliding drags refuse the move,
duplicates walk to the nearest free slot.
- Backspace / Delete on a selected layer removes it (respecting the
layer's own lock and any enclosing group lock).
- "Still frame" allowed on the last keyframe: the layer stays on stage
past its final kf. Timeline draws a solid dim tail line from the
last kf to the end, and single-keyframe tracks now show a full-span
line so on-stage/off-stage reads at a glance. Height stays 3px.
- Project name moved next to the logo, turns into a rename button on
hover (pencil fades in). Rename syncs the stored record when the
project is already persisted.
- Shadow + blur keyframes animate in the preview and exported runtime:
the runtime's lerpProps used to drop them, so every preview rendered
shadow=0 between keyframes. RUNTIME_VERSION 11 → 13 (covers the
button-mask + shadow fixes). Held-last-kf also taught to the runtime.
- Button masks render across every path: edit-mode mask-preview,
nested buttons on the main stage, sidebar thumbnails, fullscreen
preview + exports. drawButtonFrame new in render.ts.
Smaller fixes:
- Dragging layer A on the stage with a stale selection on layer B used
to move B and snap A back. Now the shift-selected branch only runs
when the dragged layer is itself in the selection.
- Clip-track row was missing its icon — PhFilmStrip was referenced but
never imported. Added, plus dropped the bespoke `gap` on clip / script
name rows so their icon+label spacing matches layer rows.
- Clip-art drawer pre-lays-out its 400px grid behind `overflow: hidden`
so slide-in reveals a finished grid instead of reflowing auto-fill
columns over 220ms.
- Timeline clip-track dropzone hides until the library has a clip; its
"drop a clip here" hint stays centred in the visible ruler area.
- Keyframe context menu: check-mark and icons share a single 12px column
so the ✓ on an easing option lines up with PhPauseCircle / PhCopy /
PhTrash on the rows below. "Still frame"'s active indicator moved to
the trailing-check slot.
- Button editor's mask-preview now shows the button's own stage instead
of leaking through to the main scene. drawButtonFrame drives it.
Regression tests cover all of the above: group-color cascade, pin,
clear-re-inherit, migration, button-kf snap and collision rules,
backspace-deletes-selected-layer (incl. lock guards + editable-target
guard), still-frame-past-end visibility, clipart drawer rigid width,
mask rendering in drawButtonFrame / drawSceneFrame, shadow + blur
interpolation in both canvas and runtime paths.
