/*
  bioLogic Design – Farben, Schrift, Abstände und Bausteine für die Website
  Version 2 · November 2026 (Feinschliff mit Impeccable, Taste Skill und Emil Kowalski)

  Die Datei lädt nichts von außen. Die Schrift Inter liegt im Ordner /fonts
  auf dem eigenen Webspace (SIL Open Font License, siehe fonts/OFL.txt).

  REGELN IN KURZ
  · Klickbar = Blau (--blue). Nichts anderes ist blau.
  · Fließtext in --ink. --ink-muted nur für Nebentext (Quellen, Hinweise, Beschriftungen).
  · Flächen unterscheiden sich durch einen Farbschritt, nicht durch Linien oder Schatten.
  · Keine kleinen Zeilen über Überschriften. Die Überschrift sagt selbst, worum es geht.
  · Sechs Schriftgrößen: Hero, Überschrift, Zwischenüberschrift, Einleitung, Text, Klein.
  · Bewegung nur mit transform und opacity, Ausklang mit --ease-out.
