WCAG 2.2 at level AA, for everything built so far and everything built later. In practice that means every screen works with a keyboard alone, every control has a visible focus state, colour never carries a meaning on its own, controls are at least 24 by 24 pixels, animation respects the reduce-motion setting, and nothing asks you to re-type what you already gave. Code fields allow pasting. Automated checks run in the test suite; keyboard, VoiceOver and NVDA passes are done by hand.

• The two drag-and-drop boards (spool locations and the request queue) have keyboard alternatives — arrow keys and the buttons on each card — but the dragging itself is not announced in detail by every screen reader.
• The colour-matching tool reads a photo on a canvas and describes the closest filament in words, but the visual comparison itself has no text equivalent beyond the colour names.
• Label PDFs and the material-note PDF are generated files; their reading order is correct but they are not tagged PDFs.

If something is hard or impossible to use, say so through the contact page. Say which page, what you were trying to do, and what you use (browser, screen reader, keyboard only). It will be read by a person and answered.
