/* Font-Loading: index.html lädt Inter + JetBrains-Mono bereits via
   <link rel="stylesheet"> mit korrektem preconnect. Der frühere base.css
   @import duplizierte das und zog zusätzlich Fraunces + Space-Grotesk
   nach (in keiner Regel referenziert) → 152 font-faces für 2 effektiv
   genutzte Familien registriert. Entfernt: spart ~80 KB render-blocking
   font-CSS + einen HTTP-Round-Trip. */
