/*
 * Heatrail partner portal: components.
 * ---------------------------------------------------------------------------
 * Every colour, size, radius and face comes from public/css/tokens.css. This
 * file names no colour of its own, so a change to the design system happens in
 * one place. Self-contained, no build step, so the portal renders anywhere.
 *
 * It used to open with its own dark palette (--bg: #0b0f17, --panel, --text)
 * and to redefine --warn and --bad, two values tokens.css already held. That
 * is why a redesign could not be done in tokens.css alone. Both are gone.
 *
 * NO INLINE STYLE ANYWHERE, and no inline script: the portal ships a strict
 * CSP with no 'unsafe-inline' (App\Http\Middleware\SecurityHeaders), so a
 * style="" attribute is silently dropped. Everything visual lives here.
