/**
 * captureHdrSequentialLoop — the legacy sequential HDR / shader-transition
 * frame loop. Single DOM session, single-threaded per-frame work. Used by:
 *
 *  - HDR renders (HDR video raw-frame sources are fd-bound to one worker)
 *  - single-worker SDR renders
 *  - the all-transition edge case (parallel workers buy nothing there)
 *
 * Sister of `captureHdrHybridLoop.ts`. Both consume the same per-frame
 * primitives from `captureHdrFrameShared.ts` so behavior parity is enforced
 * by reusing the helpers rather than by careful comment-keeping.
