Design train: unpack the complete authoritative package into design-reference

Supersedes the prior partial import. From claude.ai/design project 370ba6df:
- HANDOFF.md (the entry point — exact tokens, glyph library, liftable
  behaviors, laws)
- vyndr-mobile.html (19 mobile screens — closes all 10 previously-uncovered
  surfaces: landing/pricing/streaks/ledger×2/empty/scan/player/team/explore +
  combat/pitcher/archetypes/correlation), vyndr-system.html (desktop terminal),
  support.js
- assets/glyphs/ — all 74 archetype marks as real SVGs + MANIFEST, GENERATED
  from the authoritative glyphDefs() in the desktop file (currentColor, 24-grid,
  duotone) rather than 74 fetches. These replace the generic star/plus
  placeholders (the archetype family was never rendering as a distinct 74-mark
  system).
- removed my interim MOBILE-SPEC.md distillation (the real 19-screen file +
  HANDOFF supersede it).

Landing (desktop marketing) captured in-context — it's M2/M3-desktop scope;
raw file stays in the design project until that wave.

RECONCILE + build (token alignment, glyph lift, M1b surfaces, M3) follow.
