   • Fonts are inherited from the site (no font-family is set here).
   • Colours use the "ASLab Modern Palette" (deep forest green + sage +
     soft mint + warm off-white) supplied for this redesign.
   • Navbar and footer markup are not touched; only their accent colours
     inherit from this palette automatically via the site's own CSS vars.
   • Every class here is prefixed "hx-" so nothing else on the site is
     affected, except the small, explicitly-scoped overrides for
     .bio-section / .news-section background and .card-badge colour,
     and the .news-container layout (still carousel-free, grid based).
