/* ===========================================================================
   Homelab app theme -- the shared look for every homelab web app.
   Served from https://static.mailmasker.org/theme/v1/theme.css
   ---------------------------------------------------------------------------
   Built on the Silver Linings design system (silverlinings.llc,
   www.mailmasker.org) so the apps and the marketing pages read as one product.
   This file is SELF-CONTAINED -- an app loads this one stylesheet and nothing
   else. It deliberately does NOT @import the marketing sheet: that sheet is
   written for full-bleed marketing pages (100vh heroes, decorative arcs) and
   most of it is dead weight in an application.

   DARK ONLY. No prefers-color-scheme branching anywhere, by decision -- the
   brand is dark, and branching guarantees the apps drift apart again.
