/* gdr-tokens.css: the GDR surface palette and type scale, in one place.
 *
 * Derived 2026-08-25 from pulsefund.com, measured in a rendered browser rather
 * than eyeballed: a warm bone ground (#F4F3F3), a single clay accent used
 * almost everywhere (#95625A, 1244 occurrences on their home page), near-black
 * text (#333), light-weight display type, uppercase micro-kickers, and a
 * twelve-word lede. The Institute sits alongside Pulse, so the surfaces should
 * read as relatives.
 *
 * Two deliberate departures, both measured:
 *
 *   1. Their accent scores 4.54 against their own ground, which is under the
 *      4.5 floor once it sits on a tinted panel. They use it large and at
 *      weight 300, where the graphical 3:1 floor applies instead. Ours has to
 *      survive an 11px link, so the day accent is darkened to #8A4F44, which
 *      clears 4.5 on every surface in the set.
 *   2. Pulse is light only. This carries a night palette built from the same
 *      hues inverted, because a gated working surface gets read at night.
 *
 * Token names match what the GDR pages already use, so a surface adopts this
 * by linking it and deleting its own :root and [data-theme="day"] blocks.
 * Nothing else has to change.
 *
 * Theme contract, shared with nav.js and theme-toggle.js: data-theme on the
 * documentElement, "day" or "dark", persisted at astraeus.pm.theme. Night is
 * the default so an unstyled first paint is never white.
