Palette Enforcer — Visual Coherence

Applies color palette constraints to all generated PNG assets so every sprite, tile, and background shares the same enumerated color set. Without this, GPT Image 2 returns arbitrary colors and assets from the same game look like they came from different games.

When to use

After all art generation (sprite-artist, tile-artist, bg-artist) and before codesmith. Also run if the user says "make the art more cohesive" or "unify the palette."
