/*
 * Design tokens: the brand palette (deep forest green, cream, gold), a
 * compact type scale, spacing scale, radii, shadows, and motion easing.
 * Every other stylesheet reads from these custom properties only — no
 * hard-coded colours or sizes elsewhere, so the whole site restyles from
 * this one file. (This palette replaced an earlier near-black/gold theme —
 * grep for "ink" in class names elsewhere in the codebase and it's this
 * green, not literal black.)
 *
 * Fonts: a serif display face (Georgia — a safe, pre-installed system
 * font, no external request) for headings, paired with the existing sans
 * stack for body copy/UI — an editorial, premium feel for headings without
 * sacrificing UI legibility. See --font-display and base.css's h1–h3 rules.
