Reconcile questionnaire branch with main's site split and redesign

Post-rebase repairs after main moved 226 commits (site/ split to the
private impeccable-site repo, DESIGN.md spec now eight sections, register
extraction replaced by extractSectionValue, seed mode rewritten):

- document.md: transplant this branch's seed pipeline (assets, interview,
  visual cues, picker) onto main's rewritten file; adopt the canonical
  section vocabulary. The interplay with new-work's workshop is left for
  PR review.
- picker: vendor kinpaku tokens/kit CSS, hero art, and favicon under
  picker/ (site/ no longer exists here); drop the sharp resize step and
  ship the compressed JPEG directly; declare astro/sharp-free deps.
- picker-server: read the register via extractSectionValue('Register')
  since extractRegister is gone from context.mjs.
- palette.mjs / utils.js / test-suites.mjs / package.json / release.mjs:
  rebuild as main's version plus this branch's additions, undoing hunks
  the -X theirs replay had clobbered.
- craft.md / shape.md: reset to main (this branch's net change was zero).
- progress bar: animate transform instead of width (design hook finding).

Validation: bun run build green (prose validators clean), bun run test
198/198, picker-server suite 7/7.
