/* =============================================================================
   dashboard.css — Projects Dashboard page only (/dashboard/).

   Loaded after site.css. Reuses shared foundation classes wherever possible
   (.section, .section--alt, .section__head, .eyebrow, .display-*, .body-l,
   .caption, .chip, .chip__dot, .tile, .figure__value/__label, .btn,
   .link-more) and only adds what's genuinely new: the
   breadcrumb, the hero chip row, case-study internals (KPI tiles, filters,
   charts, insight cards, method details), the Live SQL console, and the
   methods/about grid.

   Chart colors are read from CSS variables at render time by dashboard.js
   (getComputedStyle), so they stay in sync with the site's tokens and
   re-render automatically when [data-theme] changes. --dash-mono and the
   --dash-* chart palette below are the only tokens this file adds; --dash-sky
   aliases the site's --blue so it already flips with theme. The categorical
   order (sky, orange, aqua, yellow, magenta) is the validated order from the
   dataviz skill's palette method (node scripts/validate_palette.js): with the
   site's brand blue fixed as slot 1, this ordering clears the lightness,
   chroma, CVD-separation and normal-vision checks in both themes at up to 5
   series (our largest categorical field). Dark-mode steps are re-picked for
   the dark card surface, not a flip of the light hex. --dash-heat-0/1 are the
   single-hue sequential ramp (light-to-dark blue) used by the cohort heatmap.
