/* CORAL — the house UI/UX standard (named 2026-10-05). Tokens, type, controls and the look of every Coral
   component. Behaviour is in coral.js; the showcase and its tests are index.html. Change a look HERE, never in a page.
   Built on: site.css (lasercutting, the brand tokens), standards/scrollbar.css (the pinstripe, CLAUDE.md s12),
   edtable.js (the table), NAVIGATION.md (3D). Prefix: co-.

   Layout of a Coral page: one column of content, one vertical scroll, nothing scrolls sideways. A screen
   (dashboard) does not scroll at all and pages what does not fit. */
