Button-state transitions
- State flips on stage-preview buttons (normal / hover / pressed /
disabled) now ease over 50ms instead of snapping. New
`transitions` map + rAF ticker in useButtonRuntime drive a
continuous sample time between BUTTON_STATE_TIMES slots;
CanvasStage samples each button child at that interpolated time
so keyframes at the 4 states blend smoothly. Mid-flight flips
(hover → pressed while still in normal → hover) rebase from
the current live sample instead of snapping.
Locked groups revoke edits
- Locking a layer directly or its enclosing group deselects the
layer so the Properties panel can't keep editing it. Panel also
splits into three branches — editable / locked / no-layer —
with a dedicated locked-layer hint.
- Timeline keyframe interactions (drag, dblclick-to-remove,
context menu, dblclick-to-create on lane, add-kf toolbar)
now consult effective lock (direct + parent group) instead
of just layer.locked.
Editor polish
- Inactive tracks fade as a whole row (opacity 0.5) instead of
per-child, so keyframes, segments, and still-frame tails stay
visually proportional to their active counterparts.
- Dragging a layer onto a group's track-name label now drops
it INTO the group (was previously only the group-lane area).
- Button assets on the stage show a pointer cursor on hover so
it's obvious they're interactive.
- Global CSS forces `cursor: pointer !important` on every enabled
button / role="button" so scoped component styles can no longer
accidentally shadow the default.
- Timeline resize handle jumped above the scrub-bar (z-index 100)
so the full 14px grab zone is hit-testable again.
Regression tests
- setTrackLocked deselect paths: direct lock, group lock with
selected child, group lock with unrelated selection, unlock
doesn't re-select.
- duplicateKeyframeAt: props + easing + hold + bezier copied,
collision refusal, unknown-id guards, separated-track routing.
- Button transition runtime: no-transition baseline, mid-flight
bounds, mid-transition rebase, no-op setState.
- Shared composables tooltips + asset-thumbs: same ref across
calls, localStorage round-trip.

::-webkit-scrollbar-corner was unstyled so the browser filled the
intersection of horizontal + vertical scrollbars with its default
color, which read as a ~10×10 white square in the dark theme.
Transparent matches the already-transparent track.

- background video layer (document-level), syncs to playhead in editor and fullscreen
- playback in/out brackets on the scrub ruler; i/o set them, r rewinds to in-point
- togglePlay, tick, fullscreen loop, WebM + server FFmpeg export all honor [in, out]
- top-level mask layers cascade over everything below until a group boundary
- fullscreen preview slaves localTime to the bg video so it stops stuttering
- welcome "new project" now actually loads a blank scene (was a no-op)
- default canvas background hardened to white via normalizeScene
- new keyframe button (+) in the name-spacer, backspace/delete removes selected kfs
- drag-end auto-selects the created/shifted keyframe so the path is visible
- animation path updates live during drag and spans every selected keyframe
- track rows show an icon per asset kind (rect/circle/image/text/polygon/freeform)
- default mask mode is negative, buttons read − then +
- sticky track-name columns raised above playhead/brackets; orange bracket styling
- tests for playback range, blank scene, mask defaults, cascading top-level masks
