Accessibility
The Accessibility tab in Settings — interface scale, contrast, colour vision, motion, hit targets, focus, and what the canvas announces for screen readers.
The gear icon in the top navbar opens Settings → Accessibility. Every control there is available to every signed-in or guest user on every screen size — accessibility is never behind a plan, a Power User mode or a viewport.
Interface scale
One multiplier for the whole interface: Auto / 100% / 125% / 150%. Text, spacing, icons and corner radii scale together, so labels grow without anything clipping around them.
- Auto follows your window: 100% below 2000px wide, 112% from 2000px, 125% from 3000px — a big screen starts readable without you hunting for a setting.
- An explicit choice is stored with your other settings (localStorage, plus the cloud when signed in) and applied before the first paint, so reloading never flashes back to Auto.
- Browser zoom still works on top of it, and the type floor is 11px everywhere either way.
Vision
- High contrast hardens borders, muted text and card sub-lines so text stands apart from its surface. Your operating system's increased contrast preference turns the same treatment on without you touching this switch.
- Solid surfaces removes the blur and translucency behind dialogs, menus and panels, so nothing behind the text moves while you read it. The OS reduced transparency preference does the same on its own.
Colour vision
- Colour-blind-safe tag palette repaints tags from the Okabe-Ito hues — the reference set for red-green and blue-yellow colour vision — instead of the default rainbow, whose first five colours collapse into one band for dichromatic viewers. It is applied while painting, never to the stored colour: turn it off and your original colours come straight back. Exports follow it automatically.
- Show tag initials puts each tag's first letter in its chip, so tags stay tellable apart with no colour information at all. Exported images show the same letters.
The Custom Theme Editor shows a live WCAG ratio on every colour slot that has a meaningful counterpart (4.5:1 for text, 3:1 for icons and borders), with a Fix button that applies the smallest adjustment that clears the threshold. The edit goes through the editor's normal per-section undo.
Motion
- Reduce motion stops animations — marching connections, node entrances, transitions — whether or not your system asks for reduced motion. The OS setting keeps working on its own; this switch lets you force it (or keep it off even when the OS asks, by leaving it off).
Pointer & focus
- Larger hit targets raises the button height floor and widens the invisible hit area around small controls.
- Stronger focus ring draws a heavier outline on keyboard focus, and on plain focus too, so a click-then-tab reader never lands on a control with no visible marker.
What the canvas says
- The workspace is a
<main>landmark and the Skip to main content link (first on the page when you press Tab) jumps straight into it. - Moving the selection with the arrow keys announces the card through a polite live region: name, kind, level, child count, root/dimmed/collapsed flags and tags — for example
src, folder, level 2, 12 children, tags backend. Selecting several cards announces the count instead.
