Implementation rules
Accessibility is part of the brand’s authority: it applies to words, interaction, animation and documentary imagery.
- 01Never use colour as the only signal; add a glyph and label.
- 02Keep keyboard focus visible with the approved focus token.
- 03Respect reduced-motion preferences and render the cube assembled and still.
- 04Write alt text that describes the work being done, not the mood.
- 05Keep production labels at or above 12px.
