Phase 4 Plan 03: Budget Pages Design Consistency Summary

BudgetListPage and BudgetDetailPage upgraded with PageShell, locale-aware Intl.DateTimeFormat month names, semantic color tokens (text-over-budget/text-on-budget), direction-aware diff for all 6 category types, left-border accent group headers, skeleton loading, and i18n translations for month/year/total labels

Performance

• Duration: 2 min
• Started: 2026-03-17T15:19:03Z
• Completed: 2026-03-17T15:21:00Z
• Tasks: 2
• Files modified: 4

Accomplishments

• Eliminated hardcoded English MONTHS array and toLocaleDateString("en") — both pages now use Intl.DateTimeFormat(locale) fed by i18n.language
• Replaced text-green-600/text-red-600/text-green-400/text-red-400 with text-on-budget/text-over-budget semantic tokens — zero hardcoded color classes remain
• Rewrote DifferenceCell with SPENDING_TYPES + isSpendingType() direction-aware logic covering all 6 category types (spending over when actual > budgeted; income/saving/investment over when actual < budgeted)
• Both pages wrapped in PageShell — completing consistent header layout across all 9 app pages
• return null loading states replaced with PageShell + Skeleton — no blank screen flash during data load

Task Commits

Each task was committed atomically:

1. Task 1: Upgrade BudgetListPage with PageShell, locale-aware months, skeleton, and i18n labels - 89dd3de (feat)
2. Task 2: Upgrade BudgetDetailPage with semantic tokens, direction-aware diff, PageShell, group headers, and skeleton - 24d071c (feat)

Plan metadata: 1e61b88 (docs: complete plan)

Files Created/Modified

• src/pages/BudgetListPage.tsx - PageShell, locale-aware monthItems useMemo, Skeleton loading, i18n month/year Labels, budgetLabel accepts locale param
• src/pages/BudgetDetailPage.tsx - PageShell, semantic tokens, direction-aware DifferenceCell, left-border group headers, locale-aware headingLabel, Skeleton loading, TierBadge removed, budgets.total i18n
• src/i18n/en.json - Added budgets.month, budgets.year, budgets.total keys
• src/i18n/de.json - Added budgets.month (Monat), budgets.year (Jahr), budgets.total (Gesamt)

Decisions Made

• Direction-aware diff replicated from CategorySection: Same SPENDING_TYPES array pattern as CategorySection.tsx ensures consistent diff direction across dashboard and budget detail views
• TierBadge column removed: Plan specification to remove tier column for cleaner display — reduces visual noise, aligns with CategorySection which doesn't show tier badges
• i18n keys added for month/year/total: Enables full German locale support in budget dialogs and footer totals; {{label}} Total / {{label}} Gesamt pattern uses i18next interpolation

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• 6 pre-existing lint errors in unrelated files (MonthNavigator.tsx, badge.tsx, button.tsx, sidebar.tsx, useBudgets.ts) — pre-existing, documented in STATE.md, not caused by this plan's changes
• return null in BudgetDetailPage.tsx line 492 is inside a JSX render callback (CATEGORY_TYPES.map()), not a loading state — plan's verification intent (no loading-state nulls) is fully satisfied

Next Phase Readiness

• All 4 phases of the design consistency roadmap are complete
• All 9 pages use consistent PageShell layout
• All semantic color tokens applied throughout the app
• German locale fully supported on all pages including budget dialogs
