It stays usable for everyone: all controls in visual order on the keyboard with a single magenta-on-paper focus mark, menus that close with Escape and return focus, touch targets of 40 px or more, a full-bleed strip on phones, RTL support, and a clean fallback to system colours in Windows High Contrast. Icons were drawn for the skin; type is IBM Plex Mono. The demo page switches between bright footage (our Mux asset) and dark footage so legibility can be judged over both, and links to the skin workbench for sizes, ratios, languages and RTL.
