Render a 'model comparison grid' video from a config — a fal-style "same prompt, N contenders" showcase — a dark real-DOM stage where per beat a monospace prompt fades in centered, docks to a small top strip, then a labeled 2-4 panel grid (static images OR muted video clips, mixable per cell) staggers in and holds for comparison, plus a minimal end card — frame-stepped via Playwright (video cells are frame-seeked deterministically) and encoded with FFmpeg. Deterministic assembly, FREE (cell media comes from create-image-fal / create-video-fal, music from create-music-elevenlabs), text stays pixel-crisp. Use for the model-comparison-grid format.

# render-model-comparison-grid
Render the 'model comparison grid' format from a config. The signature of this format is a
**"Same prompt. N models."** gauntlet: a dark stage where, per beat, a `PROMPT` eyebrow +
the (condensed) prompt **fades in** centered in monospace and holds readable ~0.8s, then
docks to a small top strip while a **grid of 2-4 labeled panels** staggers in (0.15s apart)
and holds for side-by-side comparison. A persistent model/variant label sits under each
panel; column order is identical on every beat. Ends on a minimal end card (headline +
column names only — **no meta-stats line**).
The grid is **media-agnostic per cell**: any cell is a static image or a **muted video
clip** (i2v outputs, screen recordings), mixable within one beat. Video cells loop during
the hold and are **frame-seeked deterministically** (the renderer awaits each seek), so the
render never depends on wall-clock playback timing.
