/* Quellstein — Thermal Spa & Wellness Trail (self_travel-11) design system:
   "Ruhebad" (calm bath). Rebuilt 2026-09-18 as part of the full
   design-SYSTEM redesign initiative — a distinctly green-tinted light
   surface (sage/eucalyptus, not cream/terracotta/ivory), a humanist-serif
   + rounded-sans pairing with soft low-contrast character, a transparent
   header that sits over the hero photo (not sticky, not opaque), a dark
   forest single-column centered footer, fully soft-shadow cards with no
   border, and generous airy spacing throughout to read as genuinely calm.
   Distinct from every other site per PROCESS.md's variable-substitution
   test. */
