/* ============================================================================
   CheckIn — Editorial / Precision-Tool Design
   ----------------------------------------------------------------------------
   Reduktion ist die Devise. Schwarz/Weiß-Surface, ein einziger Akzent, klare
   Hairline-Borders, Typografie als Hauptträger der Hierarchie. Keine Gradients,
   keine Glas-Effekte als Deko, kein Glow. Mobile-first.
   Klassen-Präfix `c-` damit das Theme parallel zur Legacy-CSS leben kann.
