Accessibility

Conformance target

This site aims at WCAG 2.2 Level AA. We believe it currently meets that bar on every page type, tested by hand rather than by a badge generator. If you find somewhere it does not, that is a defect and we want to hear about it.

What is in place

• Keyboard: every control is reachable and operable by keyboard, in a sensible order, with a visible focus ring that meets contrast requirements. A "skip to content" link is the first stop on every page.
• Structure: one h1 per page, headings in order, real landmarks (header, navigation, main, footer), and breadcrumbs marked up as such so a screen reader can announce where you are.
• Tables: data tables have column headers and a caption describing what the table contains.
• Charts: every bar is decoration only — the number it represents is written next to it as text, so nothing is conveyed by length or colour alone.
• Contrast: body and interface text meets at least 4.5:1 against its background in both the light and the dark theme; large text and interface borders meet their thresholds.
• Forms: every field has a visible, permanently attached label, errors are announced rather than shown only in colour, and the result of sending the form is announced to assistive technology.
• Motion: with prefers-reduced-motion enabled, animations, counters, parallax and tilt are switched off and content appears immediately. Nothing moves on its own, nothing flashes, and nothing auto-plays.
• Preferences respected: reduced transparency and increased contrast settings are honoured, and the light/dark choice follows your system unless you override it.
• Zoom and reflow: text scales to 200% and the layout reflows to a 320 px viewport without horizontal scrolling. Wide tables scroll inside their own container, not the page.
• Without JavaScript: all content, all numbers and the contact form keep working. Nothing essential depends on scripting.

Known limits

• Source links point to third-party pages we do not control, and those pages may not be accessible.
• Very wide comparison tables require horizontal scrolling on small screens. The same figures are available in the vendor pages in a single-column form.
• Testing is done with keyboard, zoom, reduced-motion and screen-reader passes; we have not run a formal third-party audit.
