/* ============================================================
   KRAUTH+WERNET — global.css (Produktionsdatei)
   Fonts + shared styles across all pages: design tokens, reset, page frame,
   header, contact button, highlight button, lazy load animations,
   exit transitions, custom cursor, menu, footer, and mobile overrides.
   
   Spacing principle: all fixed desktop content containers use
   bottom: min(160px, 15vh) — scales proportionally on short
   viewports (e.g. 13" laptops). Mobile breakpoints untouched.
