/* Soleuno Auslastung — alternative design.
   One idea carries the page: how full the spa is, always shown on the same
   green scale (pale = empty, deep = full; inverted to "brighter = fuller" in
   dark mode). Everything else is neutral ink on a cool off-white. Amber marks
   "now". Type: Bricolage Grotesque, self-hosted (no third-party requests).
   Shape rule: panels 20px, cells 6px, nothing else rounded. */
