Recharts v3 Cell component used for per-slice colors (still functional, deprecated for v4)

Fixed numeric height on ResponsiveContainer (180px) to avoid zero-height rendering

Zero-weight items filtered out before chart data to prevent invisible/NaN slices

Donut chart: PieChart with Pie innerRadius/outerRadius and Label position=center for hole text

Chart data transformation: group items by key, sum weights, compute percentages, filter zeroes

Pill toggle view switcher: reusable pattern for switching between data breakdowns

Accomplishments

Created WeightSummaryCard component with donut chart visualization using Recharts
Implemented pill toggle switching between category and classification chart views
Built weight subtotals display (Base | Worn | Consumable | Total) with colored indicator dots
Added custom tooltip showing segment name, formatted weight, and percentage on hover
Rendered total weight in center of donut hole using selected weight unit
Wired WeightSummaryCard into setup detail page below sticky bar (only when items exist)
Handled edge case of zero-weight items with placeholder message

Task Commits

Each task was committed atomically:

Task 1: Install Recharts, create WeightSummaryCard, wire into setup detail page - d098277 (feat)

Files Created/Modified

src/client/components/WeightSummaryCard.tsx - New component with donut chart, pill toggle, subtotals, and custom tooltip
src/client/routes/setups/$setupId.tsx - Added WeightSummaryCard import and rendering inside itemCount > 0 block
package.json - Added recharts dependency
bun.lock - Updated lockfile with recharts and its dependencies

Decisions Made

Used Recharts v3 Cell component for per-slice colors (functional in v3, deprecated for v4 removal)
Fixed 180px height on ResponsiveContainer to prevent zero-height rendering issue
Filter zero-weight entries before passing to chart to avoid invisible/NaN segments
Default view mode is "category" (most useful initial view for gear analysis)

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

Phase 9 complete: classification badges + weight visualization both functional
All 121 tests pass, build succeeds, lint clean on modified files
Recharts available for any future chart features

Self-Check: PASSED

All 3 files verified present. Task commit (d098277) confirmed in git history. recharts found in package.json. WeightSummaryCard found in $setupId.tsx.
