/* Taktreise — Classical Music & Festival Trail (self_travel-15) design
   system. REBUILT 2026-09-18 for design-SYSTEM uniqueness (round 3, after
   UK/-5/-6 and Germany). Deep indigo-violet concert-hall-at-night ground —
   a blue-violet hue, clearly distinct from -12's red-violet wine-burgundy
   and every other dark site's neutral/blue-black — with a brass-gold
   accent. Prata + Manrope is a fresh pairing (an elegant display serif
   against a clean modern grotesque), unused by any of the 8 already-
   redesigned sites. Structure/behaviour (Klangfinder branching quiz,
   Programmzettel detail-page insert card, all class names, is-current/
   is-done/is-active/is-open state hooks) is UNCHANGED — only the visual
   system changes: radius (mixed BY COMPONENT — 0 on cards/buttons, full
   pill only on small tag/kicker elements — a different radius philosophy
   from -13's uniform-diagonal or -14's uniform-14px), header (sticky with
   a thin brass accent bar at the TOP edge, not the bottom), footer (a
   4-column dark band — no other site in the series uses 4 columns), cards
   (a top-edge accent stripe only, no border/shadow/divider/flat-block —
   unused treatment), buttons (ghost text-link with an animated underline
   reveal, not filled/outlined). */
