Accessibility.
The interface is keyboard reachable, including the menu, filters, dialogs, and the brief player. Focus is visible. The ivory and ink pairing is the reading surface. Muted blue is darkened where it carries small text. Gold is used as a line, not as the only carrier of meaning.
Motion pauses. The rate ticker stops on hover, touch, the pause control, and when the system asks for reduced motion. Card images do not zoom in that case.
Charts include titles, units, and a source line. The map has a text list beside it. Ask Tiki writes its answer on the page, not only in a voice.
The brief player uses browser speech synthesis and says so. It is not a transcript of a recording because there is no recording. If speech is unavailable, the written briefs remain.
This is not a conformance claim and not an audit. A public launch should test with assistive technology and publish a route for reporting barriers.
