/* Area Redesign Digital Twin: design tokens ONLY
 * (docs/BRAND_ALIGNMENT_SPEC.md section 1).
 *
 * The :root block below is the Neighbourhood DT palette, copied verbatim from
 * aadorp-energy-dt-backend/web/index.html, so the two tools read as one product.
 * Dark is the only theme.
 *
 * No component rules in this file: those live in css/app.css (shared),
 * css/scene.css (stage-2 scene) and css/panels.css (stage-2 panels).
 *
 * Fonts are vendored into the image at build time (web/Dockerfile) rather than
 * fetched from Google Fonts, because this tool makes no CDN call at run time.
 * Family names and weights match the reference, so --font-head / --font-body
 * resolve to the same faces. Both families are SIL OFL 1.1; the licence travels
 * with the files in /vendor/fonts/<family>/LICENSE.
