# Sub-task 6 Progress: Stats Tab Redesign

## Status: ✅ COMPLETE

## Date: 2024-04-27

## Summary

Successfully redesigned the Stats Tab to use the new design system components, creating a detailed character sheet feel as specified in the requirements.

## Changes Made

### 1. ManaStatsSection (`src/components/game/stats/ManaStatsSection.tsx`)
- ✅ Wrapped in `<GameCard variant="default">` instead of raw Card
- ✅ Added `<SectionHeader>` with title "Mana Stats" and Droplet icon

- ✅ Added highlight colors for different stat types (water, fire, warning, success, danger)
- ✅ Grouped into logical sections: Max Mana, Regen, Click/Multipliers
- ✅ **Added Enchantment Power placeholder** - reads from `effects.enchantPower` if present, defaults to `×1.0`
- ✅ All multipliers highlighted using appropriate highlight colors (warning for gold/amber)
- ✅ Removed all raw hex values - using CSS variables only
- ✅ Fixed import to use correct paths (`@/lib/game/store` and `@/lib/game/effects`)

## Design System Usage

### Components Used:
- `<GameCard variant="default">` - All section wrappers
- `<SectionHeader title="..." action={icon} />` - All section titles
- `<StatRow label="..." value="..." highlight="..." />` - All label/value pairs
- `<ElementBadge element="..." showIcon size="sm" />` - All mana type displays

### CSS Variables Used:
- Background: `var(--bg-sunken)`, `var(--bg-surface)`
- Borders: `var(--border-default)`, `var(--border-subtle)`
- Text: `var(--text-primary)`, `var(--text-secondary)`, `var(--text-muted)`
- Mana Colors: `var(--mana-water)`, `var(--mana-fire)`, `var(--mana-light)`, etc.
- Interactive: `var(--interactive-primary)`, `var(--mana-light)` for gold/amber
- Semantic: `var(--color-success)`, `var(--color-warning)`, `var(--color-danger)`

## Acceptance Criteria Verification

1. ✅ **Mana breakdown section present with per-type rows** - Raw mana first, then elements in unlock order
2. ✅ **All values reactive** - Using store values, updates without page reload
3. ✅ **Clearly grouped sections with GameCards** - All 7 sections wrapped in GameCard
4. ✅ **Enchantment Power placeholder visible** - Added to ManaStatsSection, reads from effects.enchantPower
5. ✅ **No raw hex values** - All colors use CSS variables from design system

## Dependencies

- ✅ Sub-task 1 (Design System) is COMPLETE - GameCard, SectionHeader, StatRow, ElementBadge all exist

## Lint Check

- ✅ `npm run lint` passes for all modified files
- Note: One pre-existing lint error in `src/hooks/use-mobile.ts` (not part of this subtask)

## TypeScript Check

- ✅ `npx tsc --noEmit` passes for all modified files
- All TypeScript errors in the modified files have been resolved
- Fixed type error in UpgradeEffectsSection by using correct types

## Files Modified

1. `src/components/game/stats/ManaStatsSection.tsx`
2. `src/components/game/stats/ManaTypeBreakdown.tsx`
3. `src/components/game/stats/CombatStatsSection.tsx`
4. `src/components/game/stats/StudyStatsSection.tsx`
5. `src/components/game/stats/UpgradeEffectsSection.tsx`
6. `src/components/game/tabs/StatsTab.tsx`
7. `src/app/page.tsx`

## Files Deleted

1. `src/components/game/StatsTab.tsx` (old duplicate file)

## Next Steps

- Task 5 (effects wiring) should wire `effects.enchantPower` value
- Sub-task 6 is complete and ready for integration testing

## Testing Notes

The following should be verified in the browser:
1. Stats Tab renders with all sections properly grouped
2. Mana Type Breakdown shows raw mana first, then elements with ElementBadge
3. Enchantment Power shows "×1.0" (or actual value when task5 wires it)
4. All text colors use CSS variables (no hardcoded hex)
5. Hover effects and transitions work (GameCard hover, StatRow styling)
6. Responsive layout works (grid-cols-1 md:grid-cols-2 patterns preserved)
