Session G (night2): Phase 6 — landing first-paint + content engine + OG

6.1 FIRST-PAINT ROOT CAUSE: the landing blocked its ENTIRE render on
    Supabase auth init ('loading || user') — anonymous visitors stared at
    'LOADING THE SLATE' for the whole auth roundtrip (~3-4s). Now a
    synchronous localStorage session check gates the suppression: only
    visitors who actually hold a session (and will redirect) wait;
    anonymous traffic paints the hero immediately. Full RSC conversion of
    the hero is deferred and logged — the blocker itself is dead.
    Proof Strip rules: top-3 by grade whatever they are; 'TONIGHT'S TOP
    SIGNALS' only with >=1 A-tier, else 'TONIGHT'S BOARD'; nothing graded
    yet → yesterday's SETTLED reads with outcome chips (misses included).
6.2 Content routes: /api/content/top-signals/:sport,
    /streak-watch/:sport (the zero-grade daily format off the aggregator),
    /daily-report/:sport — built but self-flagging do_not_post until the
    record clears n>=20. Flag, don't fake.
6.3 Per-player OG images: app/player/[name]/opengraph-image.tsx (Node
    runtime per the S53 rule) + server layout generateMetadata — every
    shared player link unfurls as an intelligence card.
