/* =========================================================
   Derila Ergo — editorial design system
   Dependency-free, hand-written CSS. No frameworks, no build.

   Signature motif: the "contour line" — a twin-lobe curve with a
   central dip, echoing the butterfly-contour pillow profile. It
   recurs as the brand mark, the section divider, the page-header
   rule, and a background accent in dark bands. Nothing else in
   the system uses decorative shapes, so the motif stays legible.
