[m5+m6] DIRECTOR MODE + FLOW VIDEO PLATES — all lanes + sync6 seam fixes
Lane A: grammar.js (shot/angle/focal/light/mark data), presets.js (bbox shot
solver, light/mark appliers, DIRECT bar UI, NL box), stage video plates
(VideoTexture plane/corner/dome, screen kind, syncVideos), dock video cards.
Lane B: scenegod:direct → grouped-undo keys/cuts, 🗣 lip-sync from audio via
/rhubarb, Cmd+wheel zoom / wheel scroll, audio trim, video clock-follow via
nullable entityVideo seam. Lane C: POST /director (LLM proxy, server-side op
validation vs vocab+scene, mock-tested), render.js awaits stage.syncVideos.
Sync6 (orchestrator): VIDEO_EXTS in server tree/media types (video primary,
img poster as thumb), stage.entityVideo accessor, syncVideos forces
videoTex.needsUpdate (rVFC never fires in hidden tabs → black plates).
Verified: 9 server groups + timeline + presets suites green; browser SYNC:
one-click MCU framing lands camera+fov keys+cut (single undo), golden_hour
relight keys, plate scrub-follow frame-exact, finalRender mp4 shows the Flow
golden-hour street plate behind an animated character.
