| A Game of Friends — public information page at https://agameoffriends.com/ (package 040, splash slice; D-180).
| The approved kit's tokens and type (design/UI_DESIGN_SPEC_v1.md §§1–3, 6): Void/Panel backgrounds, cyan primary
| action, restrained magenta/yellow/green accents, self-hosted Chakra Petch (display) and Barlow (body), latin subset,
| SIL OFL 1.1 (assets/licenses). Standalone: nothing here is shared with the play application's stylesheets, nothing is
| loaded from another origin, and no rule can reach the game or welcome pages.
|
| Accessibility: text on Void/Panel at ≥ 4.5:1 (muted #AAB4C3 on #0C1626 is 8.3:1), status in words, visible focus,
| targets of at least 52 px, wrapping instead of clipping from 320 px, and no animation at all (the only transitions are
| hover colours, disabled under prefers-reduced-motion).
