"""Regenerate card_sources.py from the real .tsx components.

The registry's packager ships .ts but drops .tsx, so Card.tsx and Root.tsx
never reached a consumer install and `npx remotion render Card` had no Card
composition to render. A .py file ships, so the components travel inside one.

The .tsx files stay canonical — edit those, then run this. A test asserts the
two never drift.

Usage:
  sync_card_sources.py            # rewrite card_sources.py
  sync_card_sources.py --check    # exit 1 if it is stale
