/* style.css — Gymnasium Gerresheim · Offene Lernzeit (OLZ)
   Design concept: the digital hall pass.
   OLZ runs on physical-world artifacts — the attendance ticket, the
   punch card, the stamp in the Klassenbuch. Surfaces borrow that
   vocabulary: dashed tear-lines, punched holes, stamped status marks.
   Readability pass: mono type is now reserved for short labels only —
   every paragraph, list and input uses the body face at a larger size,
   and borders/contrast were strengthened throughout. */
