/* Area Redesign Digital Twin: layout + shared components
 * (docs/BRAND_ALIGNMENT_SPEC.md section 2).
 *
 * Geometry and primitives come from the Neighbourhood DT reference
 * (aadorp-energy-dt-backend/web/index.html): a full bleed scene with floating
 * glass over it, so the two tools read as one product.
 *
 * Owned by stage 1. Stage-2 agents must NOT edit this file: scene styles go in
 * css/scene.css, panel styles in css/panels.css (both load after this file, so
 * they can extend or override).
 *
 * Quality badge classes are driven by the quality STRING coming from the API
 * (js/util.js: PocUtil.qualityBadge). Nothing here is per device.
