/* ============================================================
   D. & L. Koch Verlag — 2026 Redesign
   Design note: the publisher's own catalog language — cloth
   binding, foil stamping, thread-stitching, ISBN precision —
   is the material this design is built from. Two accent colors
   trace the house's two actual editorial lines (Medizingeschichte
   / Kulturgeschichte); the "colophon" label block, styled after
   a library catalog card, is the one signature motif, repeated
   everywhere a book appears.
   ============================================================ */

/* Google Fonts are loaded via <link rel="preconnect"/"stylesheet"> in generate.py's
   head() template (not @import here) — avoids the extra render-blocking round-trip
   an @import forces before the font request can even start. */
