* fix(studio): add smooth preview zoom with pinch/Ctrl+scroll - Scale iframe content from inside (contentDocument.documentElement) instead of scaling the parent div, avoiding compositor re-rasterization on every zoom frame — critical for smooth zoom on high-refresh displays (240Hz) - Document-level capture-phase wheel handler bypasses the DomEditOverlay - Center-based zoom (no pan drift from pointer-anchored formulas) - Transient HUD shows zoom % briefly, no persistent UI controls - Double-click preview area to reset zoom to fit - Drag-to-pan when zoomed past 100% - Momentum scroll suppression after pinch gesture (400ms cooldown) - Delta clamping (MAX_DELTA=10) prevents overshooting on fast gestures - toDomPrecision rounds transform values to 4 decimals (matches tldraw) - Zoom state persisted to localStorage with 200ms debounce - Exposes --preview-zoom CSS custom property for overlay coordinate mapping - Fix infinite render loop in NLELayout (onIframeRef → refreshPreviewDocumentVersion) * fix(studio): use CSS zoom instead of transform scale for preview zoom CSS transform: scale() on a div containing an iframe causes compositor cross-layer sync issues that produce visible frame tearing on high-refresh displays (240Hz ProMotion). CSS zoom property changes the actual rendered size without compositor layer synchronization, eliminating the jumping. - Replace transform: scale(Z) with zoom: Z on the stage div - Keep transform: translate() for panning (compositor-friendly, no iframe) - Overlays work correctly since getBoundingClientRect() includes zoom - Remove will-change, transition hacks, pointer-events toggles * fix(ci): use apt-get for ffmpeg in preview-regression workflow The FedericoCarboni/setup-ffmpeg action downloads from an external URL that has been persistently unreachable, causing CI failures. Switch to apt-get install which uses Ubuntu's package repos (same as ci.yml and player-perf.yml). * fix(studio): clear zoom timers on NLEPreview unmount settleTimerRef, hudTimerRef, and retiringTimerRef could fire after component unmount. Add cleanup effect to prevent stale callbacks. * feat(studio): persist sidebar, timeline, and playback speed across reloads Wire up studioUiPreferences for the three remaining UI states requested in #752: left sidebar collapsed, timeline visibility, and playback rate. All three now survive page reloads using the same localStorage key as preview zoom.
