/* =====================================================================
   CONEWER design system - shared by the customer app (/app/), the
   captive portal (index.html) and the connected page (status.html).

   Two hard constraints shape everything here:

   1. NOTHING EXTERNAL. The captive portal renders before the customer has
      internet, so a web font or CDN would hang the page. System fonts,
      inline SVG icons, this one same-origin file.

   2. CHEAP TO PAINT. Android's captive-portal WebView is a weak renderer;
      a full-screen backdrop blur has blanked the page there before (see
      the note in the old index.html). Glass is opt-in behind @supports,
      over an opaque fallback, and only on small cards.

   Dark-first on purpose: the portal is opened outdoors in sun and late at
   night, and a dark sheet with one bright accent reads well in both.
