Render the React-Three-Fiber-v9 (React 19) templates client-side without touching the
React-18 Next host: a standalone Vite app (services/remotion/player) mounts
@remotion/player with the real FlexStory composition. The studio will embed it via an
iframe and feed scene data (URL hash for first paint, postMessage for live edits).
- player/main.tsx: reads {props, aspect, watermark}, computes duration via
calcFlexStoryMetadata, renders <Player>. Free tier shows a watermark overlay
(preview only — clean export stays server-authorized).
- vite.config.player.ts: builds to player-dist/ with relative base (servable at /player/).
- @remotion/player + vite added.
Verified: vite build bundles FlexStory + three.js (672 modules → 1.3MB) and serves
at /player/index.html (200). Browser render to be confirmed.
