/* Area Redesign Digital Twin: panel styles
 * (docs/BRAND_ALIGNMENT_SPEC.md sections 2 and 4).
 *
 * Owned by the stage-2 "panels" agent. Loads after css/app.css, so rules here
 * may extend or override the shared components.
 *
 * This file adds only what is genuinely panel specific: the KPI card grid, the
 * uPlot hosts, the PM2.5 bars, the 48 h scrubber and the Data sources panel.
 * Everything else (.card, .badge, .chip, .kv, h4.sub, .loading, .footnote,
 * .muted, .small) comes from app.css, which carries the Neighbourhood DT
 * primitives verbatim. Type weights follow that reference: 10px uppercase
 * badges, 11px uppercase h4.sub, 12.5px body, var(--r2) radii on cards.
 *
 * Dark is the only theme. Colours come from the brand tokens in css/tokens.css;
 * there are no raw palette values here except the tinted chip backgrounds the
 * reference itself spells out.
 *
 * Provenance chips are NOT styled here: .badge and .q-measured / .q-derived /
 * .q-synthetic live in app.css and are chosen from the quality STRING by
 * js/panels.js, never per device.
