/* ==========================================================================
   ChampPay — PAGE ARCHITECTURE
   Added 2026-08-04 when the site went from one page to fifteen.
   Everything here extends the Day-and-Night system in main.css rather than
   replacing it: same tokens, same two grounds, same engineered type.
   ========================================================================== */

/* ------------------------------------------------------------ 1. Page head
   Interior pages open on a compact night band rather than a full photographic
   hero, so the home page keeps its scale advantage and interior pages get to
   the point inside one screen. */
/* Both of these are night grounds, so they must remap the semantic tokens the
   way .on-night does — not just set `color`. Without this, anything using
   var(--fg-soft) (kickers, breadcrumbs, .code, .t-body) renders in light-mode
   ink on a near-black ground: legible-looking in a screenshot, 2.8:1 in fact. */
