/* Recall - styles tuned for cognitive accessibility.
   Design choices, all deliberate for a brain-injury audience:
   - One highly legible typeface (Atkinson Hyperlegible, built for low vision)
     used everywhere, so the eye never has to adjust between faces.
   - A calm, low-saturation "fog" palette. No pure white (glare) and no pure
     black (harsh edges). Plenty of luminance contrast for text.
   - Large type, wide line spacing, short line lengths, big touch targets.
   - One thing on screen at a time; one accent colour for the action that
     matters most right now.
   - Meaning is never carried by colour alone (every state has a text label).
   - Motion is minimal and fully removed under prefers-reduced-motion. */
