Accessibility.

What we do

Semantic structure. Pages are built on semantic HTML with labeled controls, so assistive technology can parse them. Data tables use real table markup with header cells — including the endpoint catalogs and pricing tables.

Keyboard navigation. Every action is reachable without a mouse, and focus stays visible.

Contrast and meaning. Body text and key actions are designed against WCAG AA contrast ratios on the Paper/Ink system. Signal Red is never the only carrier of meaning — status and connections are also labeled in text.

Reduced motion. We respect prefers-reduced-motion; animation stands down when your system asks it to.

Zoom and reflow. Layouts reflow instead of breaking at 200% zoom and beyond. Figures set in monospace tabular numerals stay legible at size.

Known gaps

We are honest about where we fall short. Charts and chain diagrams are the standing risk area: every published diagram carries a text alternative that conveys the same figures, and where it does not yet, that is logged here as a gap — not omitted. No page-specific gap is currently logged; reports to data@atcstw.com are added here as they are confirmed.

Report a barrier

If something here does not work for you, that is our bug: data@atcstw.com. Accessibility reports are triaged as defects, not feedback, and fixes ship in the normal flow with a note on this page.
