/* beats-koppelingen.css: the Koppelingen wall on the product page (spec 09, 2026-11-01). Four rows of system names, each a strip that drifts
   sideways without end (koppelingen.js moves it, faster while the visitor scrolls, the other way on a scroll up) behind a soft fade at both edges.
   The marks are the single path brand icons of Simple Icons (CC0, see vendor/LICENSES.md) drawn in the ink of the theme; a system without a
   free mark is set as a wordmark in the site type. No boxes, no borders, no colour but ink, and kobalt under the pointer. Reduced motion or a
   static page (html.beats-static): the strips wrap into plain rows inside the content width and nothing moves. Cap 16 KB (MAP amendment 3). */
