UI Plan 2 Implementation Notes

Block 01 Baseline Map

1. Sidebar and app shell currently render through apps/focus_flow_flutter/lib/widgets/sidebar.dart, apps/focus_flow_flutter/lib/widgets/app_shell.dart, and the FocusFlowHome parts under apps/focus_flow_flutter/lib/app/home/.
2. Navigation state is not implemented yet. Sidebar hard-codes Today as active, and FocusFlowHome owns only Today controllers. UI Plan 2 should add app-level section state in the home/composition layer before rendering the Backlog board.
3. Backlog board data needs new public scheduler application read models. The current BacklogQueryResult is list-shaped and returns raw Task values via BacklogItemReadModel, which is not enough for board columns, summary, detail drawer metadata, or suggested slot previews.
4. Existing commands include quick capture to backlog, schedule backlog item to next available slot, move flexible tasks to backlog, remove task, and break up task. Push-to-Someday and non-destructive backlog archive still need command-level decisions before the drawer actions can be final.
5. UI Plan 1 components to reuse include FocusFlowTokens, the dark shell, timeline reward icon, difficulty bars, selected overlay patterns, and the top-bar icon/segmented-control styling conventions.
