Phase 1 Plan 1: Design Primitives Summary

shadcn chart/collapsible primitives with Recharts v3 patch, two-tier OKLCH category colors, semantic budget status tokens, and bilingual dashboard i18n keys

Performance

• Duration: 3 min
• Started: 2026-03-16T11:12:04Z
• Completed: 2026-03-16T11:14:52Z
• Tasks: 2
• Files modified: 5

Accomplishments

• Installed shadcn chart and collapsible UI primitives with Recharts v3 initialDimension compatibility patch
• Extended OKLCH color token system with two-tier category colors (dark text + lighter fills) and 3 semantic budget status tokens
• Added 6 new dashboard i18n keys to both en.json and de.json at full parity

Task Commits

Each task was committed atomically:

1. Task 1: Install shadcn primitives and patch chart.tsx - d89d70f (feat)
2. Task 2: Extend color tokens and add i18n keys - 4f74c79 (feat)

Files Created/Modified

• src/components/ui/chart.tsx - ChartContainer, ChartTooltip, ChartTooltipContent wrappers with initialDimension patch
• src/components/ui/collapsible.tsx - Collapsible, CollapsibleTrigger, CollapsibleContent radix primitives
• src/index.css - Extended @theme inline block with semantic status tokens, chart fill variants, darkened category text colors
• src/i18n/en.json - 6 new dashboard keys (carryover, vsBudget, overBudget, underBudget, onTrack, loading)
• src/i18n/de.json - Matching 6 German dashboard keys at parity

Decisions Made

• Applied initialDimension={{ width: 320, height: 200 }} patch since shadcn CLI still generates without it (PR #8486 not yet merged)
• Category text colors darkened to ~0.55 lightness for WCAG 4.5:1 contrast against white card background
• Chart fill variants kept lighter at ~0.65-0.70 for non-text use with 3:1 minimum contrast
• Investment hue adjusted from 290 to 285 for better OKLCH gamut representation

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

• Pre-existing lint errors found in badge.tsx, button.tsx, sidebar.tsx, and useBudgets.ts (5 errors total). These are not caused by this plan's changes and have been logged to deferred-items.md. Build passes; lint failures are in unmodified files only.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Chart and collapsible primitives ready for Plan 02 component composition
• Color tokens and i18n keys available for all subsequent dashboard UI work
• No blockers for Plan 02 execution

Self-Check: PASSED

All 5 created/modified files verified present. Both task commits (d89d70f, 4f74c79) verified in git log.
