# accessibility-settings.screen

## Components
|
|
|
|
| Component | Notes |
|
|
|---|---|
|
|
| Display | Type / motion / contrast / color-blind palettes. Stakes-color override changes [F §F1](./00-system-visual-system.md) low/medium/high palette. |
|
|
| Voice & audio | VoiceOver labels, TTS preferences, register override (forces hearth/working/plain everywhere). |
|
|
| Interaction | Replacements for gesture-based affordances (pinch, swipe). Single-tap approvals replace swipe-to-approve. |
|
|
| Content | Image alt-text from `content-*` specialists; plain-language toggle suppresses culinary metaphor. |
|
|
|
|
## States
|
|
|
|
1. **Default (inherits iOS)** — all top-level toggles match iOS settings; explicit overrides clearly marked.
|
|
2. **Override active** — chip on overridden rows: "Override of iOS setting."
|
|
3. **Color-blind selected** — preview swatch of new stakes palette appears inline.
|
|
4. **Plain-language enforced** — banner: "All Cocotte copy is in plain register. Hearth + working registers are suppressed."
|
|
5. **Reduced haptics on** — confirmation chip "Cocotte uses one haptic per event, not two."
|
|
6. **VoiceOver** — section read in order; overrides explicitly announced.
|
|
|
|
## Interactions
|
|
|
|
- **Tap any toggle** → commits immediately + recorded as audit row (per brief I — accessibility changes are auditable).
|
|
- **Tap "Override font size"** → iOS-style size picker.
|
|
- **Tap palette preview** → expands swatches comparison.
|
|
|
|
## Edge cases
|
|
|
|
- **Color-blind palette conflicts with brand accent** (rose) — alt palette uses amber/blue for stakes, preserves brand accent elsewhere.
|
|
- **Single-tap approvals on a multi-surface card** (per H §H4) — replaces per-surface checkboxes with toggle list, single tap on Approve commits all selected.
|
|
- **VoiceOver with cook-mode requested** — cook-mode disables; VoiceOver gets primary audio.
|
|
- **Reduced motion + streaming reply** — replaces token-fade with full-message snap-in.
