- Add ui/components/ExpandedFab.kt with ExpandedFab + MiniFab helpers; HomeScreen and ExpenseListScreen both consume it, the tab-collapsing LaunchedEffect in ExpenseListScreen is hoisted to its Content()
- Inject GetExpenseSummary in HomeScreenModel; drive summary via dateRange.flatMapLatest { getExpenseSummary.await(it) } (fixes the period-filter total-card flicker) and drop the inline combine(expenses, dateRange) recomputation
- Hoist isFabExpanded out of HomeScreenModel into HomeScreen.Content() so the FAB state is local to the composable
- Convert HomeScreenModel.exportToCsv from a callback to a suspend fun returning Result<Unit>; the screen does the snackbar dispatch on the coroutineScope
- Consolidate DateRangeOption label mapping to a single DateRangeOption.labelRes() / .labelText() pair (one source of truth)
- Rename FAB string keys to shared fab_manual / fab_import and drop the home_fab_* duplicates
- Update docs/04-implementation-plan.md and .opencode/agent/implementor.md Charts sections to reflect the Vico 2.0.0 column-chart-with-legend substitution (Vico 2.0.0 has no pie layer)
