/* mar500.com staging, /_assets/v4_1_overrides.css
 * Loaded last so its declarations win against the inline base stylesheet.
 *
 * v4.2 (2026-05-06):
 *   1. Eyebrow-style rail for cross-domain related findings, positioned
 *      between the page eyebrow and the H1. Replaces the old bottom-of-
 *      page 3-card grid which v4.1 could not fix with CSS alone (parent
 *      <main> uses non-wrapping flex).
 *   2. .note-substrate one-line provenance inside the .note block at the
 *      bottom of the page, replacing the heading-area .revision-notice.
 *
 * Color discipline (locked 2026-05-06):
 *   Nav-related color bars default to NAVY ink inactive, GOLD-DEEP active.
 *   Burgundy and green are reserved for critical alerts and semantic
 *   positives respectively, never for nav/wayfinding chrome.
 *
 * The v4.1 grid overrides on section.related-findings are intentionally
 * dropped: the v4.2 patch removes that section outright, so those rules
 * are now dead code.
