/* tejaswee shared stylesheet, v1
 *
 * Every custom property lives on :root. Projects change one thing, --accent, through
 * data-accent on <body> (set from projects.yaml). Gold stays the link and focus colour
 * everywhere so the family reads as one site.
 *
 * Dark mode follows prefers-color-scheme; theme.js lets a reader pin light, dark or gold,
 * which sets data-theme on <html>. Gold is only ever pinned: the system never picks it.
 *
 * Bump the /assets/v1/ segment for breaking changes so browser caches don't fight you.

 * A deep-gold reading of the light theme, in the family of a panchang page: a dusky
 * gold ground, a lighter gold for cards, dark brown ink, bronze and maroon. Nothing is
 * near-white, so it glares less than light. Every pairing is checked: ink 8.1:1 on the
 * ground and 9.5:1 on cards, muted 5.5:1, gold-deep 5:1, the ground on every accent fill
 * at least 4.9:1, gold hairlines 3:1. Accents are darkened here because they carry the
 * ground as text; gold as an accent fill steps down to gold-deep for the same reason. */
