# Research: Accessibility Palettes & Glyph Legibility

## Hypothesis
CSS variable-driven palettes can satisfy WCAG AA while remaining legible for common color-blind conditions.

## Questions
- Contrast ratios for default and high-contrast themes
- Visibility of mood hue under protanopia/deuteranopia/tritanopia
- Glyph legibility at small tile sizes

## Method
- Prototype palettes; run through color-blind simulators and Axe
- Validate glyph size/contrast on sample tiles

## Acceptance
- AA contrast for focus indicators and glyphs
- Verified palettes for three color-blind modes

## Deliverables
- Approved palettes, token list, glyph sizing guidance
