/* ============================================================================
   EcopanGEM — Flux Analysis Studio
   Design system: "Data-Dense Dashboard" (ui-ux-pro-max), Fira Sans / Fira Code,
   full light + dark. Every class the studio JS generates is styled here; the DOM
   contract (77 ids, ~110 classes) is unchanged, this is a reskin.

   Rule that shapes the whole thing: DATA SURFACES STAY ON WHITE PAPER in both
   themes. Escher maps and Plotly charts render their own light SVG, so a dark
   plot well would just frame a white rectangle. Chrome is themed; the science is
   printed on paper.
