   FR4 DESIGN SYSTEM — one shared stylesheet for the tpl_flugraum4 template
   and every mod_fr4_* module (per FR4_MODULE_GUIDELINES.md §6).

   Tokens are carried over from the brand's design.md (Nimbus token set),
   reinterpreted for FLUGRAUM4, an event venue at Flugplatz Eisenach-Kindel:
   the cyan/navy palette reads as sky + hangar-at-night, and the signature
   motif is runway edge-lighting + a slow radar sweep behind hero sections -
   literal to the subject, not a decorative default.
