Primary fix: setTeamTimers now bails out with `return prev` when the
value hasn't changed, preventing a full DraftRoom re-render on every
1-second timer tick (was 33% of profiler samples).
Memoization: wrap AvailableParticipantsSection, TeamsDraftedGrid,
QueueSection, SidebarRecentPicks, and DraftGridSection in React.memo
so timer ticks don't cascade into heavy components that don't use
timer state.
Stable refs: wrap nine action handlers in useCallback and extract two
inline arrow functions from props objects so memo() comparisons
actually bail out. Memoize the { numFlexPicks } object passed to
TeamsDraftedGrid.
socketVersion: expose an incrementing counter from useDraftSocket so
the socket handler effect re-registers on socket recreation.
Async cleanup: add abort flag + in-flight guard to the visibilitychange
JWT refresh handler to prevent concurrent executions and stale state
updates after unmount. Add abort flag to useDraftNotifications
permissions.query() to prevent dangling onchange if unmounted
mid-promise.

* Add push notifications implementation plan
Documents the approach for adding a browser Notification API toggle
to the draft page sidebar, including files to create/modify and
edge cases to handle.
https://claude.ai/code/session_0149MvVUYDY6pFUAV1fL4K69
* Add browser push notifications toggle to draft page
Adds a Notifications toggle in the draft sidebar (below Autodraft)
that uses the Browser Notification API to alert users when a pick is
made or when it's their turn, while the tab is not focused.
- New useDraftNotifications hook for state, permission, and localStorage
- New NotificationSettings component with Switch toggle
- Fires "It's your turn to pick!" when the next pick is the user's
- Fires "{Team} picked {Player}" for all other picks
- Gracefully hides toggle when Notification API is unavailable
https://claude.ai/code/session_0149MvVUYDY6pFUAV1fL4K69
* Fix all code review issues with push notifications
- Extract snake draft order calculation to shared getTeamForPick()
helper in lib/draft-order.ts, removing the duplicated logic
- Fix notification firing on user's own picks (guard with team id check)
- Fix notification firing after draft is complete (early return)
- Use a ref for sendNotification to prevent full socket handler
re-registration every time the toggle is changed
- Add permission drift listener via Permissions API so the UI reacts
if the user revokes notification permission in browser settings
- Add SSR guard for document.hidden in sendNotification
- Remove redundant isSupported prop from NotificationSettings;
derive unsupported state from permissionState === "unsupported"
- Move NotificationSettings out of QueueSection prop-drilling path;
render it via a new settingsSection slot on DraftSidebar instead
https://claude.ai/code/session_0149MvVUYDY6pFUAV1fL4K69
* Fix second round of notification code review issues
- Add My Turn Only / All Picks mode granularity so users can choose
to only be notified when it's their pick, or for every pick
- Remove double top-border by stripping leftover border-t/pt-4/mt-4
wrapper from NotificationSettings (now provided by DraftSidebar)
- Remove unused isSupported from hook return value
- Add n.onclick = () => window.focus() so clicking a notification
brings the draft tab back into focus
- Scope localStorage keys to userId to avoid shared-browser conflicts
(keys now: draftNotifications-{userId}-{seasonId})
- Add notificationsModeRef alongside sendNotificationRef so mode
changes don't trigger full socket handler re-registration
