/* Neil Bartholomew portal (neil-bartholomew.pages.dev). Design system paf (PAF Editorial), sibling of
   platinum-k9-training.pages.dev. Shared tokens, reset and components for the chooser page and design options
   A, B ("Night ops" dark theme) and C (light "Hangar" theme, class .theme-hangar on <html>).
   Parallax: js/parallax.js sets --p on [data-parallax] (0 at viewport centre, +1 one screen below, -1 one
   screen above) and --scroll on <html>; layers move with translate3d only. Moving layers are never clipped by
   their own box: only the page edge (html, body overflow-x: clip) and full-width bands clip. Mobile first. */
