 * Tokens come from the tool itself: the One Dark roles dok's default theme
 * paints with, and the #0a0a0a the casts are rendered on, so a screenshot and
 * the page around it are the same surface.
 *
 * Shape rule, applied everywhere: surfaces 12px (the radius baked into the
 * rendered casts), controls 6px. Nothing else.
 * Colour rule: green is the only accent in page chrome. The other roles appear
 * only where they mean what they mean in dok's own output — syntax, status.
 * Iconography is dok's own glyph set (├─ └─ ● ✔ ✖ →), set as text.
