   OCTANEWS — public site stylesheet.
   Dark, editorial, glassy: the same navy ground, radial glows and
   strings canvas as the /admin shell (and every Circloud app), so the
   public site and the dashboard read as one product. Brand tokens come
   from /assets/brand-colors.css; the header shell from app-header.css.
   Category colour flows through ONE custom property, --cat, set by the
   .cat-<slug> classes the page emits (see render.js categoryStyles).
