Session E (night2): Phase 4 — scan + parlay polish

4.1 ROOT CAUSE of 'Ohtani returns nothing': no backend
    /api/players/search existed (MLB 404'd; NBA/WNBA hit the offline
    Python service). New Express route + mlbStatsAdapter.matchPlayers —
    canonical nameKey fuzzy match (exact > last-name prefix > folded
    substring). LIVE-VERIFIED vs the real 1,299-player list: Ohtani /
    Aaron Judge / Sánchez / sanchez / Chisholm Jr all resolve; accented
    and unaccented return identical results. Non-MLB matches the
    platform's cached names (rosterlogs + grades), cache-only.
4.2 Reveal choreography per §7: analyzing steps → DECLASSIFIED stamp →
    90ms-staggered context panels (entrance floors visible per the
    Phase-0 rule); prefers-reduced-motion skips straight to the card.
4.3 PRIOR READS chips on scan results — the model's public ledger
    history for the player (deferred-render, outcomes + pending, never
    invented). /api/ledger/model gains ?player= on entries.
4.4 Parlay Lab: humanized stat labels via the ONE shared formatter
    (lib/gradeAdapter.statLabel); 1-leg provisional grade ('Leg grade:
    B — add a leg for the combined read'); discoverable entry — Nav
    'Parlay Lab' item opens the drawer via window.__openParlay, and the
    open drawer now renders an honest empty state at 0 legs.
