/* Bartholomew Driving School. Design system: PAF Editorial (`paf`), "Night ops" dark theme, as on
   platinum-k9-training.pages.dev. Client-brand adaptation (brief §6): --signal-red is the accent fill (buttons,
   bars, stripes, markers) with white type on it; never red text on dark. Motifs: the L plate (red L on a white
   square) in the places paf uses chevrons (dividers, corner marks, bullets), and the red door stripe of the cars
   as section rules. Parallax: js/parallax.js sets --p on every [data-parallax] element. Mobile first. */
