/* Wiederverwendbare Plain-CSS-Komponentenschicht für statische/Server-
   gerenderte Projekte (kein React/Build-Step) – Struktur 1:1 aus
   Relaunch2026/marberg/assets/css/styles.css übernommen, hier aber
   ausschließlich gegen die BESTEHENDEN _shared/Design-Tokennamen
   geschrieben (core-colors.css/core-typography.css/core-spacing.css +
   eine brand-*.css), damit sie für jede Marke funktioniert, ohne eigene
   Farbvarianten je Klasse (siehe .btn-primary: keine .btn-yellow-Variante
   nötig, weil --text-on-brand markenspezifisch in der jeweiligen
   brand-*.css sitzt).

   Radius-/Schatten-Mapping gegenüber Relaunch2026 (eine Stufe versetzt):
     Relaunch --radius-sm (14px) -> hier --radius-md
     Relaunch --radius-md (22px) -> hier --radius-lg
     Relaunch --radius-lg (32px) -> hier --radius-xl
     Relaunch --radius-pill      -> hier --radius-full
   --shadow-card/-hover/--shadow-image sind neue, additive Tokens in
   core-spacing.css (gleicher Name wie in Relaunch2026, keine Übersetzung
   nötig). --content-max (Relaunch) entspricht exakt --container-max hier
   (1180px). --ink -> --text-primary (Textrollen) bzw. --sand-900 direkt
   (dunkle Flächen). --ink-mute -> --sand-300 (heller, gedämpfter Text auf
   dunklem Grund). --transition -> var(--duration-base) var(--ease-standard).

   Einbindung: nach core-colors.css, core-typography.css, core-spacing.css
   und genau einer brand-*.css. */
