/* ============================================================
   Michael Höbling — personal homepage
   Plain modern CSS: custom properties, Grid/Flexbox, fluid type,
   automatic dark/light mode. No frameworks, no build step.

   Typeface: self-hosted IBM Plex Sans / Mono (see fonts/, and
   "Typeface" in README.md). Sans carries the voice, Mono is the
   data voice (dates, labels, meta) — nothing else in Mono.
   Structure is hairlines and a left rail, not cards and shadows.
