## Profile Behavior

The preset row applies an authored bundle of existing settings rows and feature
groups. Each profile supports one-click apply, preview before apply, undo-last
preset, per-profile persistence, and startup restoration before gameplay.

- Vision impaired: HUD scale, camera shake, reduced motion, readable font,
  letter spacing, and color palette.
- Hearing impaired: captions, visual cue, haptic companion, HUD scale, reduced
  motion, and camera shake emphasis.
- Motor impaired: one-handed controls, QTE alternatives, timing extensions,
  global game speed, and sequential combo input.
- Cognitive: objective clarity, puzzle skip thresholds, adaptive difficulty,
  readable font, and letter spacing.
