Settings get a page of their own for accessibility, with presets on top
(screen reader, low vision, dyslexia, focus, keyboard and motor, motion
and seizure safe, deaf and hard of hearing) that change several options
at once and can be undone, then the options by topic, and a reset.
Text size used to be a fixed 14/16/18px on the root, which threw away
the size people set in their browser. It is now a percentage of the
browser's size, from 87.5% to 200%. Motion, contrast and transparency
follow the system by default and can be overridden either way; the
old Animations switch becomes Reduce motion. The visual options are
applied before the first paint, so the page no longer flashes at the
wrong size.
- `lib/accessibility-settings.ts`: the new settings, their allowed
values, and the code that writes them onto `<html>`
- `app/accessibility.css`: bundled fonts (Atkinson Hyperlegible Next,
Lexend, OpenDyslexic), text spacing, a focus outline that survives
Windows contrast themes, more-contrast colours on any theme, reduced
transparency, a large pointer
- admins can preset every new option but lock only shortcuts, send
confirmation and the notification duration; a lock on text size or
another reading aid works as a default
- always-light mail and toolbar labels now sync, and imports drop
values the page doesn't know
- font size and animations move off Appearance, the plain text font
off Reading; everyday settings such as conversation view and undo
send show on both their own page and Accessibility
