feat(skill): route fixes, delivery report, composition diversity, platform refresh

- route table: extension route for products with an existing visual
  language, feedback row, derived state tokens stay local
- completion: blocking 0 plus reported unverified; hard-gate surface is
  the touched scope; delivery report starts with what and how to open
- design.md created at step 0 with a skeleton, fingerprint line and
  change log; product-surface rubric reading; direction delegation
  states the chosen card and reason
- layout: hero families, nav forms, footer forms; art-direction page
  convergence 6 axes; genre sections; image treatments; placeholder
  conventions; multi-screen order; Tailwind theme mapping
- platform: scroll-driven examples, anchor positioning, canvas OT,
  three/R3F pins, shadcn style prefixes, Safari 26 notes, subgrid
- design-gate: four result states, exit codes, cwd module resolution,
  --url/--out-dir/--strict, oklch contrast, dead selector word match
- Korean font budget split from the Latin baseline
