/* home.base.css — minimal base layer for index.html.
   Replaces home.vendor.css (Bootstrap 5 + Start Bootstrap "Resume", 11,300
   lines / 2,488 rules). Only 74 of those rules ever matched this page; the
   rest were unreachable. Everything reachable is reproduced here with the
   Bootstrap custom properties resolved to literal values, so no --bs-* layer
   is needed.

   Cascade order: _tokens.css -> home.base.css -> home.css.
   home.css remains the editorial overlay and must load last.

   Deliberately NOT ported: the vendor `section { display:flex; align-items:
   center; padding:5rem 1rem; max-width:75rem }` and its 768px `min-height:
   100vh` — home.css overrode all of them, so the pair only existed to be
   fought. Also not ported: `a { text-decoration: none !important }`, whose
   !important silently suppressed every underline this site declares. */
