   base.css, but components.css is public-only marketing furniture (hero,

   docs/plans/ for the shell split. The .btn/.cta overrides left behind in
   components.css (.hero-full .btn, .cta-band .cta-band__btn, header.site nav
   .cta) are all two selectors deep, so they out-specify this base rule and
   win regardless of which file it lives in or which order the two are linked.
   `.cta-band__btn` used to be a single class here — a specificity TIE with
   .btn, decided by source order alone — and was scoped to fix exactly that. */
