Desktop MP4 export renders frames from a hidden BrowserWindow via
capturePage, pipes PNGs to a bundled ffmpeg (libx264/yuv420p/+faststart),
and writes the file through an atomic temp-file swap. It shares scene
validation (shared/renderValidation.cjs) and the render.html renderer with
the standalone Puppeteer server, which is hardened in parallel.
Render worker & main (electron/):
- abortable render loop with an inactivity watchdog and cancel plumbing
- atomic temp-file + rename so a cancel/failure never truncates a
pre-existing target (#7); stdin EPIPE / early-exit / backpressure-hang
handled (#8)
- HiDPI frames normalized to canvas size (#10); odd dimensions padded to
even (#13, also server); backgroundThrottling disabled (#12)
- reject canvases larger than the display (#11); single-render guard;
isolated render session that blocks network requests (#5)
Tests:
- Electron harnesses (scripts/verify-*.cjs) for capture, export, cancel,
timeout, assets, background, capture-fidelity, resolution, odd-dims,
aggregated by verify-desktop-render.cjs
- server smoke + e2e and shared validation unit tests
- headless hook (src/devtools/headless.ts) to run the in-app suite under
browser/electron hosts; pixel-diff util + capture fixtures (test/)
- dev_docs plans: integration, fixes (#7-#13), and the e2e/capture strategy

Tooltips
- New v-tooltip directive + TooltipHost floating panel replace the
native title attribute across 95+ sites (topbar, timeline, sidebar,
properties, stage overlays, fullscreen preview, export dialog,
clipart drawer, modals). Styled dark card with a configurable
label + optional help line for inline documentation; screen
readers still get an aria-label when the panel is disabled.
- Settings → Interface toggle (`ruwio:tooltipsEnabled`) hides the
visual panel for users who know the app. IconButton now routes
its title prop through v-tooltip so every existing call site is
tooltip-aware without churn.
Editor-hide + export filter
- New `Layer.editorHidden` flag, eye toggle per layer row, skipped
by the Konva stage and the mask-preview canvas path but honoured
by exports and fullscreen preview (runtime untouched).
- Export dialog gets a "Skip hidden tracks" switch that strips
editor-hidden layers from every format (scene JS, runtime,
example HTML, MP4, WebM) on opt-in. Disabled when the scene has
no hidden layers.
Button editor
- `+` buttons appear on empty state slots in button-timeline rows
and duplicate the nearest keyframe (prev by preference, next
otherwise) onto that slot. New `duplicateKeyframeAt` store
action carries props, easing, hold, and bezier handles across.
Stage / interaction
- Plain left-click on the empty content view pans the viewport,
but only when the pointer isn't over a Konva shape — transformer
handles, vertex dots, and selection boxes that extend past the
canvas edge keep their drag.
Settings reshuffle
- Timeline tab merged into Document (Duration + FPS sit under a
new "Timing" sub-heading). New Interface tab gathers three
global prefs: Show tooltips, Show locked tracks, Asset
thumbnails — driven by shared composables so the existing
toolbar toggles stay in sync. Interface-tab CSS defensively
resets the scoped label flex-column + uppercase rule that was
making the toggle row look like an accident.
Project identity + UX polish
- Favicon wired up (moved to public/favicon.ico, linked from
index.html); scripts/pack.sh packs the minimum Vue project
(src, index.html, configs, public) into a tarball with the
right version in the filename, and `npm run pack` drives it.
- About dialog now credits Torsten Hoeltge.
Test infra
- Progress bar turns red mid-run on the first failure: runAll
gets an onResult callback that TestOverlay uses to push each
result into the reactive array incrementally.
- mountComponent in the test harness registers v-tooltip on the
isolated app instance so IconButton's aria-label contract
actually fires under test.
Regression tests
- duplicateKeyframeAt: copy fidelity (props, easing, hold),
collision refusal, unknown-id guards, separated-track targeting.
- Shared composables: useTooltipPref and useAssetThumbsPref both
return the same ref across calls and persist to localStorage.
- Tooltip contract: IconButton ships `aria-label` (not title);
live-DOM smoke tests match on aria-label selectors now.
