Phase 05 Plan 01: Design Token Foundation Summary

One-liner: Established sharp-cornered OKLCH pastel design foundation with --radius: 0 cascade, raised fill chroma to 0.22+, deleted redundant chart color vars, and set chart bars to radius={0} with square legend dots.

Tasks Completed

Task	Name	Commit	Key Changes
1	Edit design tokens and add CSS overrides in index.css	99b5b5f	--radius: 0, chroma 0.22+, deleted chart vars, warmed bg, Recharts/Sonner overrides
2	Update chart Bar radius props and remove rounded-full	4c74dec	SpendBarChart radius={0}x2, IncomeBarChart radius={0}x2, ExpenseDonutChart legend dot square

What Was Built

index.css Changes

• --color-background chroma raised from 0.005 to 0.01 (warmer background)
• --color-chart-1 through --color-chart-5 deleted (6 lines removed — no remaining consumers)
• All 6 --color-*-fill variables raised to chroma 0.22+ for vibrant pastels:
  • income: 0.19 → 0.22, bill: 0.19 → 0.22, variable-expense: 0.18 → 0.22
  • debt: 0.20 → 0.23, saving: 0.18 → 0.22, investment: 0.18 → 0.22
• --radius changed from 0.625rem to 0 — cascades sharp corners to all shadcn components
• .recharts-rectangle { rx: 0; ry: 0; } override added (SVG attribute approach)
• [data-sonner-toast] { border-radius: 0 !important; } override added

Chart Component Changes

• SpendBarChart.tsx: Both <Bar> elements changed from radius={4} to radius={0}
• IncomeBarChart.tsx: Both <Bar> elements changed from radius={[4, 4, 0, 0]} to radius={0}
• ExpenseDonutChart.tsx: Legend color dot span: removed rounded-full from className

Verification

All acceptance criteria confirmed by grep and build:

• --radius: 0 present in index.css
• --color-chart-1 through --color-chart-5 absent from src/
• radius={0} present (2 matches each) in SpendBarChart and IncomeBarChart
• rounded-full absent from ExpenseDonutChart
• .recharts-rectangle and [data-sonner-toast] present in index.css
• bun run build exits 0 (TypeScript + Vite both pass)

Deviations from Plan

None — plan executed exactly as written.

Known Stubs

None — all token values are real OKLCH colors wired to actual chart and UI components.

Threat Flags

None — pure CSS/visual changes with no trust boundary impact.

Self-Check: PASSED

• src/index.css exists and contains all required tokens
• src/components/dashboard/charts/SpendBarChart.tsx contains radius={0}
• src/components/dashboard/charts/IncomeBarChart.tsx contains radius={0}
• src/components/dashboard/charts/ExpenseDonutChart.tsx has no rounded-full
• Commit 99b5b5f exists (Task 1)
• Commit 4c74dec exists (Task 2)
• Build passes cleanly
