/* blog-rail: de gedeelde blogmodule van de niche-previews.

   Eén horizontale rail voor mobiel en desktop: native scroll-snap voor touch,
   slepen met uitloop en muiswiel voor de muis, pijlen, pijltoetsen, een
   voortgangsbalk met teller en een onderwerpfilter. Recept: het gedeelde
   Rail-component in de app (src/components/ui/Rail.tsx), vanilla vertaald.

   Merkkleuren komen per preview mee als custom properties op de sectie
   (--ms-blog-*), gezet door scripts/sync-niche-blog-sections.mjs uit
   scripts/blogs/data-*.mjs. Cosmetische defaults staan in :where() zodat de
   eigen .eyebrow/.section/h2-regels van een preview altijd winnen; alleen de
   rail-layout zelf staat hard, want die moet elk raster van een preview
   overrulen zonder dat we dat raster kennen. */
