/* Overstap — design system REBUILT 2026-09-18 (round 6 of 6, Netherlands,
   final group of the full design-SYSTEM redesign initiative). The prior
   system shared the exact same CSS architecture as every other site in the
   series — flagged directly by the user. Rebuilt from scratch: a very pale
   warm dusty-rose-white "porcelain" ground (`#f7f1ee`, a genuinely
   different hue-family from every other light site — not blue-tinted like
   `-16`'s ice-blue-grey, not golden like `-14`'s gold-cream, not green
   like `-11`'s sage), a strong brick-red accent (canal-house material,
   avoiding blue entirely since `-22` already claims a Delft-blue accent),
   Bitter (slab-leaning transitional serif) + Sora (geometric grotesk body)
   — a fresh pairing, no mono face at all (a genuine absence, distinct from
   every other site which uses one). Cards and buttons use a "gable" shape
   — large radius on the TOP corners only, square bottom — evoking canal-
   house stepped-gable rooflines, a mechanism no other site uses. Header is
   non-sticky with an alternating brick-red/white dashed bottom border
   (canal-bridge-railing motif). Footer is LIGHT and THREE columns with
   thin vertical brick-red dividers (every other site's footer is either
   dark or 1-2 columns). Content, images, and link/page structure are
   unchanged — CSS-only rebuild; selector names match the HTML/JS exactly. */
