Accessibility Palette

Accessibility palettes modify information channels without changing game identity.

| Mode | Replacement strategy |

| --- | --- |

| Deuteranopia | Red/green states become blue/yellow plus shape and icon support. |

| Protanopia | Danger uses value, icon, and orange/red pairing instead of red alone. |

| Tritanopia | Blue/yellow distinctions gain magenta/cyan/value alternatives. |

| Low Vision | Increase foreground contrast, reduce background saturation, enlarge UI state shapes. |

Accessibility rule: no critical state may be communicated by hue alone.
