remotion-builder (name unchanged)

What it does. Motion graphics as code. A script or outline becomes deterministic Remotion scenes in any locked style family — data-clean charts and stats, glass-dark tech, kinetic type, social vertical, blueprint, editorial cutout. One sceneSystem.ts locks palette, type and motion; plain-English direction compiles to spring/interpolate with prop controls on every value. Map scenes from real geography, a FAL asset pipeline with background removal, a particle / dot-world engine, a master sequence synced to the VO, and every scene dual-exports as a MotionKit preset.

Why it exists. Exact on-screen text, charts, counters and re-renders are things a video model cannot promise. Code can. LIBRARY FIRST: it searches the user's existing Remotion components before building new ones.

Not for. AI-video clips (mograph-builder) or cinematics (action-builder).

Input	the brief, a script or beats, an existing Remotion project (MotionKit recommended)
Output	Remotion scenes + sceneSystem.ts, rendered MP4, MotionKit presets
Needs	Node, a Remotion project; FAL key only for generated assets
Spends	nothing to render; FAL per asset if used

Setup

python scripts/setup.py. State lives in ~/.frmwrkd/remotion-builder/ (or $REMOTION_BUILDER_HOME). transcript.py and logos.py are borrowed from the sibling mograph-builder; install both.
