VYNDR 2.0 conversion, Phase G (the systems that make the design alive). All 5
wired. Frontend-only; zero backend changes.
- lib/parlayMath.js: correlation model (0.62/0.34/0.06/0) + parlayGrade penalty
+ grade->odds + combined odds (frontend; backend parlayService unchanged).
- lib/oddsFormat.js: fmtOdds across american/decimal/fractional/implied with the
totals-pass-through rule (safer than the prototype's parseAm, which would
mis-convert 228.5) + region presets.
- lib/prefs.js: applyPrefs sets <html data-*> (the S33 a11y CSS layer) + load/save.
- lib/liveTick.js: single tick engine (SSR/test-safe, no auto-start, fresh state).
- lib/checkout.js: checkoutUrl(plan).
- LiveLayer (useLive/LiveNumber/HeartbeatBar) under the Nav ticker; GlobalHosts in
layout applies prefs + registers __prefs/__goPaywall/__checkout + hosts the
Preferences and Paywall modals. Nav read-meter is now a paywall trigger.
Gotchas: useEffect can't return a Set.delete unsub directly (boolean != cleanup);
header grew to 124px so layout paddingTop + Slate sticky-top updated to match.
18 new tests. Backend 1872 -> 1890, 146 suites, zero regressions. Web build clean.
