/* =========================================================================
   COPERNICUS-ALIGNED — light, institutional, and not a dashboard.
   =========================================================================
   The dark console with coloured accents reads as a product demo whatever the
   accents are. This page's claim is that it is a TECHNICAL RECORD, and the
   register a European due-diligence reader expects for that is a document:
   paper ground, black-blue text, hairline rules, one institutional blue, and
   colour only where it carries meaning.

   The blue is Copernicus Marine's own. That is not decoration by association —
   the sargassum product, the currents, the waves and the licence quoted in the
   footer are all theirs. Borrowing the agency's visual language is the honest
   move where inventing a house palette would be pretending the data is ours.

   CONTRAST MEASURED AGAINST BOTH GROUNDS, not eyeballed. Every token below
   clears 3.0:1 for graphics and all but four clear 4.5:1 for body text; the
   four that do not (muted, assumed, sev-0) are never body text. Audited
   2026-09-11.

   THE TWO SEPARATIONS SURVIVE, as they did through the dark palette:
     · `synthetic` sits off the severity ramp and off measured/modelled.
     · `unknown` sits off the ramp too — an unobserved coast must never borrow
       a pale severity colour, which is how "nobody looked" becomes "nothing
       there".

/* cuenca.css — RX-OS chrome for the basin-scale sargassum animation.
 *
 * Shares the panel / chip / btn / select / toast rules with playas.css
 * (the RX-OS Fleet idiom) so this screen sits beside the beach console
 * without a second visual language. Depends on rx-tokens.css.
 *
 * ONE DELIBERATE DEPARTURE FROM playas.css
 *   There the panels float ON TOP of a full-bleed map. Here they do not: the
 *   canvas is a contained card and the panels dock in the margins around it.
 *   The reason is the export. What paint() draws is exactly what the GIF
 *   encoder receives — title, colour bar, source line and the DATOS SIMULADOS
 *   badge are inside the picture, not in the page chrome. A panel parked over
 *   a corner of that picture would hide the very marker the export exists to
 *   carry, and would tempt someone to move the marker out of the frame to fix
 *   the collision. So the picture keeps its whole area and the chrome stays out.
