name: combat-ui-pattern-a description: Implement Split-Panel Combat UI (Pattern A) for SHINOBI WAY game. Use when user wants to create the horizontal confrontation combat layout, character panels, action dock, phase header, VS divider, or any component from the Pattern A combat UI system. Guides through component creation following the established architecture.

Combat UI Pattern A - Split-Panel Implementation

This skill guides implementation of the Split-Panel Combat UI, transforming the vertical theater mode into a horizontal confrontation layout.

Implementation Workflow

Step 1: Identify Target Component

Ask user which component to implement:

1. CombatLayout - Start here for new implementation
2. PhaseHeader - Top status bar
3. ConfrontationZone - Battle area with both panels
4. CharacterPanel - Individual character display
5. VSDivider - Center emblem and effects
6. ActionDock - Bottom skill bar
7. QuickActionCard - Compact skill card variant
8. MainActionCard - Large skill card variant

Step 2: Load Component Reference

Based on selection, load the appropriate reference:

• Layout/Structure: See layout-specs.md
• Component Props: See component-interfaces.md
• Styling Guide: See styling-tokens.md
• Animation Specs: See animations.md

Step 3: Generate Component Code

Follow the component template pattern:

Copyimport React from 'react';
import { cn } from '@/lib/utils'; // if using cn utility

interface ComponentNameProps {
  // Props from component-interfaces.md
}

export const ComponentName: React.FC<ComponentNameProps> = ({
  // destructured props
}) => {
  return (
    <div className={cn(
      // Base styles from styling-tokens.md
      // Conditional styles
    )}>
      {/* Component content */}
    </div>
  );
};

Step 4: Wire to Combat.tsx

After component creation:

1. Export from components/combat/index.ts
2. Import in Combat.tsx
3. Replace corresponding section
4. Pass required props from existing state

Quick Implementation Commands

Create All Files (Scaffolding)

Copy# Create directory
mkdir -p src/components/combat

# Create all component files
touch src/components/combat/{index,CombatLayout,PhaseHeader,ConfrontationZone,CharacterPanel,VSDivider,ActionDock,QuickActionCard,MainActionCard}.tsx

Barrel Export Template

Copy// src/components/combat/index.ts
export { CombatLayout } from './CombatLayout';
export { PhaseHeader } from './PhaseHeader';
export { ConfrontationZone } from './ConfrontationZone';
export { CharacterPanel } from './CharacterPanel';
export { VSDivider } from './VSDivider';
export { ActionDock } from './ActionDock';
export { QuickActionCard } from './QuickActionCard';
export { MainActionCard } from './MainActionCard';

Props Mapping from Existing Code

From App.tsx → Combat.tsx (unchanged)

Copyplayer: Player
enemy: Enemy
turnState: 'PLAYER' | 'ENEMY_TURN'
turnPhase: TurnPhaseState
combatState: CombatState
onUseSkill: (skill: Skill) => void
onPassTurn: () => void
onToggleAutoCombat: () => void
autoCombatEnabled: boolean

Combat.tsx → New Components

Copy// PhaseHeader
turnState, turnPhase, combatState.approach

// ConfrontationZone
player, enemy, playerStats, enemyStats

// CharacterPanel (player)
character: player, stats: playerStats, variant: 'player'

// CharacterPanel (enemy)
character: enemy, stats: enemyStats, variant: 'enemy'

// ActionDock
skills: player.skills, turnPhase, onUseSkill, onPassTurn

Migration Strategy

Phase 1: Layout Foundation

1. Create CombatLayout.tsx with CSS Grid
2. Create placeholder components
3. Add feature flag in Combat.tsx

Phase 2: Component Extraction

1. Implement CharacterPanel (extract from PlayerHUD + CinematicViewscreen)
2. Implement ActionDock (extract from skill grids)
3. Implement PhaseHeader (extract from inline indicators)

Phase 3: Visual Polish

1. Add VSDivider with effects
2. Implement animations
3. Adjust floating text positions

Phase 4: Cleanup

1. Remove old theater mode code
2. Remove feature flag
3. Update tests

Reference Files

• layout-specs.md - CSS Grid structure, responsive breakpoints
• component-interfaces.md - TypeScript interfaces for all components
• styling-tokens.md - Colors, spacing, typography tokens
• animations.md - Animation keyframes and transitions

Output Format

Generate TypeScript React components with:

1. TypeScript interface for props
2. Tailwind CSS for styling (matching existing codebase)
3. Responsive classes (mobile fallback to vertical)
4. Memoization where appropriate (React.memo for cards)
5. Accessibility attributes (aria-labels, roles)

Existing Code References

When implementing, reference these existing files:
