Summary

• Replaces the legacy ALLIANCE PICKER (binary ALLY/ENEMY toggles) with a TEAM ASSIGNMENT panel in SetupScene
• Each of the 8 player slots (YOU + up to 7 AI) shows color-coded team buttons: [A] [B] [C] [D]
• Clicking a button assigns that slot to a team; players on the same team become allies in-game

How it works

• Initializes config.playerTeams from DEFAULT_SLOT_TEAMS = ['A','B','C','D','A','B','C','D']
• On launch, playerTeams is spread into the SkirmishConfig passed to GameScene
• GameScene already handles this at line 313: calls deriveAlliancesFromTeams() → setAllianceMode() → win condition uses isEnemy() ✓
• No GameScene changes needed — the backend was already complete

Default behavior

• 1–4 players: all on different teams (A/B/C/D) → Free-for-all
• 5–8 players: teams repeat (5=A, 6=B…) → 2v2, 3v3, or 4v4 by default, adjustable

Team colors

Team	Color
A	Blue
B	Red
C	Green
D	Yellow

Test plan

• Open SetupScene — verify TEAM ASSIGNMENT panel appears below AI OPPONENTS stepper
• Default: slot YOU=A, AI 1=B (shown with blue/red highlights)
• Click a different team button — verify it highlights and previous deselects
• Increase AI count — verify new AI slots appear with correct default teams
• Launch with 2 AI, set YOU+AI 1 = Team A, AI 2 = Team B → YOU and AI 1 should be allies, AI 2 is enemy
• npx tsc --noEmit → pass
• npx vitest run → 62/62 pass
