Second-version artifacts for claude-opus-4-8-cc, generated one-shot:
- pelican-cycling-2.svg: hand-authored seaside SVG of a pelican on a bicycle
- mythos-craft-2.html: Three.js voxel world (Perlin terrain, WASD + mouse
  look, break/place, marble temple + crystal spires + floating isle)

Registers both as file-keyed array variants with bilingual provenance
notes; contributor OHMFOHS. Passes scripts/validate-data.ts.
