+SHIPPED + DEPLOYED: model pipeline (rolling CV confirmed v4; isotonic layer
+validated LOFO and shipped), 1 in-play timeline, 2 odds-movement chart,
+5 upset meter, 6 bracket what-if, 7 qualification scenarios, 8 compare page
+(doubles as 10 H2H explorer), 9 Elo history charts, 12 model diary,
+13 favorite team, 14 daily digest, 15 search palette, 17 offline banner,
+18 a11y pass (charts/bars labelled; reduced-motion was already global),
+20 share/OG meta.
+
+DEFERRED, with cause:
+- 3 notifications (Web Push): needs an SW strategy change (generateSW →
+  importScripts) and real-device permission testing — too risky to land
+  blind on the live site mid-tournament. Next session's headline.
+- 4 shootout live view: no real shootout payload exists until the knockouts
+  (June 28+); build against real data then.
+- 11 golden boot: ESPN only gives scorer names inside free-text event
+  strings — parsing is fragile; needs a structured source first.
+- 16 calendar strip: substantially covered by Predict's day-grouped
+  "All upcoming" view; revisit only if navigation still feels lacking.
+- 19 perf pass: bundle is ~476KB main + lazy recharts; fine for a precached
+  PWA. Revisit if Lighthouse says otherwise.
