Accessibility

This page says what has actually been tested. It does not claim conformance with a standard, because no formal audit has been carried out and a claim without one would be worth nothing.

What has been checked, and how

Verified by driving the built site in a browser and reading the resulting DOM — not by inspection of the source.

Links that leave the site. Each one carries its destination host and “opens in a new tab” in its accessible name before activation, rather than signalling it only with an icon or only after the fact. This follows the W3C technique for announcing new windows.

The leave-site dialog. A native modal dialog, so focus is trapped and the rest of the page is inert. Escape closes it — the browser’s own handling was found not to fire here, because something else on the page cancels the key first, so it is closed explicitly instead. Focus returns to the link that opened it, whichever way it was dismissed. Clicking outside dismisses it.

Keyboard operation of that dialog — tab order, Escape, focus return — was exercised with real key events, not synthetic ones.

Layout at 375 px and 1280 px, in both light and dark schemes. The page body never scrolls horizontally; wide tables and code blocks scroll inside their own containers.

Navigation entries fit on one line at the sidebar width, so the menu reads as a list rather than as wrapped prose.

The wordmark is announced as the single word “SecDockBlue” rather than as three fragments, despite being styled in three parts.

What has not been checked

Stated plainly, because the gaps matter more than the list above:

• No screen reader has been used on this site. Accessible names were read out of the DOM. That is not the same as hearing how a page is announced.
• Contrast ratios have not been measured against the WCAG thresholds. The colour scheme is Starlight’s default with one accent changed, and the accent was chosen for appearance rather than by calculation.
• No automated accessibility scan is part of the build.
• Keyboard traversal of whole pages has not been walked — only the dialog.
• Zoom to 200 % and 400 %, and reduced-motion preferences, are untested.
• Long code blocks scroll horizontally, which is a known friction for keyboard and screen-magnifier users. It is the platform default here and has not been improved on.

Underlying platform

The site is built with Astro Starlight, which handles landmarks, skip links, heading structure and the mobile navigation. Those come from the framework and have not been separately audited here. The parts written for this site are the external-link handling, the dialog, the citation blocks, the evidence blocks, the wordmark and the footer — those are what the findings above cover.

Reporting a barrier

If something here is unusable for you, that is a defect and worth reporting. Open an issue on the repository, describing what you were trying to do and what happened. A report naming a concrete barrier is more useful than any statement on this page.
