/* ==========================================================================
   Theme: "Reading Room" — content-first and typographic.
   Archivo carries headings, nav, labels, and buttons. Source Serif 4 carries
   body copy. No card shadows or heavy radius anywhere — hairline rules do
   the separating. One pine-green accent, used only for links and controls.

   Header/footer/nav are styled via Tailwind utility + component classes
   directly in each page's HTML (see tailwind-config.js for .btn/.nav-link/
   .container-page). Everything below covers what Tailwind utilities in the
   markup don't: hero, cards, forms, the terms modal, and the prose template.
