Appendix F Accessibility ← Back to the findings

Accessibility, measured on this site.

A summit with two slopes: a green ramp rising on the left, gray steps on the right, arriving at the same platform.

This page holds the site to the same rule as the product, which is that nothing on it is promised and each claim was measured. The figures below come from this site's stylesheet and structure, and wherever you can check a claim yourself, right now, on the page you are reading, we say how.

The whole instrument works from the keyboard

Each finding on the main screen is a plain address, a link to an anchor. The whole instrument navigates by keyboard alone. Tab reaches each control, Enter opens it, and the browser's back button retraces your steps, because each state you visit is a real place in the address bar.

The one small script on that screen only keeps the animation clock and the tab title in step. Switch JavaScript off and each state still opens, because the navigation is the address itself and no script handles the click.

To check this, press Tab until a finding on the main screen takes focus, then press Enter, then press Back.

Each text pairing clears the contrast floor

We computed these ratios from this site's palette. None of them is an assertion. Body text against the page background measures 11.1:1. The weakest text pairing anywhere on the site measures 5.6:1. The accessibility floor for body text is 4.5:1, so each pairing on the site clears it with room to spare.

Color does not carry a meaning on its own. Wherever the green marks something (a shackle, a plateau, a signature), a word or a shape carries the same meaning beside it.

Each section is a native browser element

The sections of each appendix are native disclosure elements. The browser provides their keyboard behavior and their screen‑reader semantics, so there is no script of ours to get them wrong. Focus is always visible: each interactive element carries a focus ring drawn in the site's text color, and no rule suppresses it.

Tab through this page: each section header opens or closes with Enter or Space, and with a screen reader on, each one is read out.

Animations stop when your system prefers reduced motion

Each transition on this site sits behind the reduced‑motion media query. When your system prefers reduced motion, the animations on this site stop. The same figures and states remain, without the movement.

Switch on Reduce Motion in your system settings and reload, and the page loads with nothing moving.

What this page does not claim

We make the claims above because they are mechanical: the ratios were computed, the anchors were counted and the media queries are present. We do not certify what it is like to use the site with a screen reader. This site has not been through an audit by a person who uses a screen reader daily, and that is the only audit of that experience that counts. If your team runs one and finds a fault, we will fix it and this page will say so.
