-- **Hands-free** continuous listening in live mode.
-- Big, labelled buttons for low vision + a **high-contrast / larger-text** toggle.
-- Keyboard focus rings, ARIA labels, haptic feedback; respects the OS *reduced-motion* and *more-contrast* settings.
+## Accessibility — the starting point, not a coat of paint
+Iris was designed for a blind user **first**, so the whole interface gets out of the way:
+- **The whole screen is one button** — tap to describe, hold to ask, double-tap for live mode. No precise targets to find, no menus to navigate.
+- **It talks first.** Spoken onboarding on the first interaction, and you **choose your language by voice**.
+- **Hands-free** continuous listening in live mode — once it's on, no buttons at all.
+- **For low vision too:** big, clearly *labelled* buttons (real SVG icons, not emoji) and a **high-contrast / larger-text** toggle.
+- **Built to standard:** keyboard focus rings, ARIA live regions, haptic feedback, and it honours the OS *reduced-motion* and *more-contrast* settings.
