/* ==================================================
   UNSUPPORTED BROWSER  (/your-app/unsupported)
   Two-panel "fork-in-the-road" rendered when the
   visitor's browser fails the support check. Top
   panel offers the technical fix (install a current
   browser); bottom callout offers the human fallback
   (call or email support).

   Why two panels, not one card with a sub-section:
   the technical and human paths are equal-priority
   alternatives, not a primary CTA with a fine-print
   escape hatch. Stacked cards make that read.

   Defensive baseline: this page assumes nothing about
   JS or modern browser features. tel: and mailto:
   work everywhere. CSS custom properties are honored
   by every browser except IE11, which falls back to
   declared defaults — page still reads, just without
   tokens.
