/* Alpenglühen — Alpine Four-Season Playbook (self_travel-13) design system.
   REBUILT 2026-09-18 for design-SYSTEM uniqueness (round 3 of the
   country-group pass, after UK/-5/-6 and Germany). Cool glacier-slate dusk
   ground with a warm alpenglow-coral accent — a dark palette, but blue-grey
   in hue, clearly distinct from -5's neutral true-black, -7's blue-black
   navy, and -12's red-violet wine-burgundy. DM Serif Display + DM Sans is a
   fresh pairing (elegant high-contrast serif + humanist geometric sans),
   unused by any of the 8 already-redesigned sites. Structure/behaviour
   (Höhenlagen-Regler slider, Höhenband detail-page scale, all class names,
   aria-selected/is-open state hooks) is UNCHANGED — this file only changes
   the visual system: background, type, radius philosophy (asymmetric
   diagonal corners — a genuinely different radius PHILOSOPHY, not just a
   different pixel value), header (sticky + gradient bottom accent, no
   border/shadow), footer (light putty block inside an otherwise dark site —
   unused pattern so far), cards (flat tinted-surface colour blocks, no
   border/shadow/divider), buttons (solid coral, same asymmetric radius). */
