S6 (a1): display — the full picture under the grammar

- specs/ROW-GRAMMAR.md: the row grammar law (slot order, color law, mark
  law, mobile stacking, no-truncation), locked by tests/unit/rowGrammar.
  StatStrip violations fixed: MovementChip before the grade (market
  context before model output); ViabilityChips after the archetype
  (identity is one contiguous run).
- Line-movement sparklines: intradayRefreshService.trackHistory captures
  real {t,line} points per grade (seeded with the lock, deduped when
  flat, capped 24) inside the snapshot write-back; StatStrip.LineSparkline
  renders at >=3 points (green toward / amber against / dim flat).
- Last-10 dot strips: services/last10Dots (streaksService accessors) ->
  /api/snapshot/:sport attaches last10_dots from rosterlogs:{sport};
  StatStrip.DotStrip renders vs the LOCKED line, newest first.
- CLV distribution: getModelAggregate emits clv_distribution (7 signed
  buckets, outliers clamped) only past the centralized n>=20 gate;
  ledger MODEL header renders the bar strip.
- Global search: SearchModal (cmd-K via GlobalHosts + window.__search),
  players via /api/players/search per sport + static lib/teams.js
  (soccer deliberately absent); Nav search icon + Search first in the
  mobile More sheet. Explore tab untouched.
- Landing LCP: fade-up floored at opacity .6 (hero h1 contentful on
  first frame, S33 visible-floor rule) + IBM Plex Mono preload:false
  (4 decorative font files off the slow-4G critical path).

2654 -> 2698 tests (226 suites) green; web build exit 0.
