           — based on Smartisan OS 8 on Smartisan R2; cross-checked on a real R2.
   Every value below was read from the Figma nodes; the comment after a rule
   names the Figma component it reproduces. See references/inventory.md.

   Usage:  <link rel="stylesheet" href="smartisan.css">, put class="s-page" on
           <body>, inline icons-sprite.svg, then use the .s-* classes.
   State:  every pressable component styles :active AND .is-pressed, so you can
           render a static "pressed" sample. Disabled = :disabled or
           [aria-disabled="true"]. Selected = :checked / aria-selected /
           aria-pressed / aria-current as noted per component.
