/*
 * Opicka — course archive and course page.
 *
 * White canvas throughout. Navy is a button and panel colour now, not a
 * page background. Ink stays for headings, gold for rules and accents,
 * bronze for accent text.
 *
 * Everything is namespaced under .opk. Several selectors are doubled
 * (p.opk-p.opk-p) where Astra's entry-content and link rules would
 * otherwise win on specificity — that is why the archive H1 was invisible
 * and why course overview text rendered link-blue.
