/* Co-work shared components. Used by BOTH the expert portal and the owner panel, so a
 * button, a field, a card or a chip looks and behaves the same on either side.
 * Every value comes from ds/tokens.css; a colour literal here is a decision made outside it.
 *
 * The language: calm, airy, thin lines, light type, borders over shadows. Hover only
 * shifts to the muted background or darker text, never moves anything; buttons nudge
 * down 1px when pressed.
 *
 * Page-specific layouts stay with their page (index.html, admin.html, panel/, kanvas/).
 * A pattern that appears on two pages moves here instead of being copied.
