+## Frontend ↔ Backend Wiring (Session 25 — non-obvious)
+A new Express route under `/api/*` is NOT reachable from the browser until
+a matching **Next.js proxy route** exists at `web/src/app/api/.../route.ts`
+that forwards to `${BACKEND_URL}/api/...`. The browser hits the Next origin,
+not Express directly. This bit us: schedule/gamelines/streaks/hotlist
+endpoints worked on Express but 404'd in the UI for two sessions. When
+adding a backend endpoint the frontend calls, ALWAYS add the proxy too
+(pattern: `web/src/app/api/odds/nba/route.ts`).

+Tank01 betting-odds real shape: sportsbooks are TOP-LEVEL keys on each
+game object (`{ awayTeam, homeTeam, bet365:{...} }`), not a `sportsBooks`
+array. Filter `NON_BOOK_KEYS` to extract books (see `gameLines.js`).
