/* ========================================
   WORLD: PFP FORGE
   Community PFP generator. Lab-specimen framing:
   a single composited "specimen" card on the left,
   trait controls on the right. Parchment palette,
   serif display, mono labels, orange accents.

   Assets are wired later via /assets/pfp/manifest.json
   (see docs/pfp-generator.md). Until then the canvas
   draws procedural placeholder art so the tool is fully
   functional. Nothing here assumes real assets exist.
