Session 42: Player Intelligence System — archetypes, stat strips, player profile, enhanced cards (2011 tests)

Built from the Claude Design "VYNDR Player Intelligence" bundle (10 sections).

- Archetypes: src/services/archetypeService.js — 41 archetypes (15 NBA / 5
  WNBA-unique / 15 MLB / 6 soccer), classify -> primary+secondary+blend.
  Frontend visual map web/src/lib/archetypes.js (colors verified == backend).
  ArchetypeBadge (full/ghost/tint + glyphs) + ArchetypeBlend (DNA bar).
- StatStrip (compact/expanded): player name once, horizontal mono stats,
  inline GradeBadge props, onPlayerClick -> profile.
- Stats API: extended src/routes/stats.js with /player/:name, /leaders,
  /game/:id (rate-limited). Aggregation in playerIntelService.js (sanitizes
  name param; grades cache; graceful on cold cache). Next proxies added.
- Player Profile /player/[name]: all 9 design sections, graceful empty states.
- Enhanced GameCard (MLB pitchers + player-grouped StatStrips) + GradeResultCard
  (archetype strip + stat context + VYNDR intelligence, optional/self-hiding via
  gradeAdapter.buildIntelFields). Player-name links wired everywhere.
- Settings page replaces the S41 redirect (account/subscription/notifications/
  display/responsible-play/danger-zone with DELETE-gated delete). LINKS to the
  real /settings/security MFA page — does not replace it. + BookChip.
- Bonus: Stats Explorer /explore (real /api/stats/leaders leaderboard); added
  Explore + Settings to Nav MORE.

Deferred (need data pipelines, Session 43): Team Hub, Offseason Intel, Slate
redesign, Stats Explorer sub-panels.

Backend 1940 -> 2011 tests (+71), 157 suites. Web build clean (exit 0).
