/* Barracks Ledger — the marketing site's one stylesheet.
 *
 * Shared by every page under site/. Moved out of index.html on 23 Sep 2026 when
 * the site grew from one page to five, so the pages cannot drift apart.
 *
 * Colour rules (SESSION-PROTOCOL §2.6):
 *   --reserved is brass and has ONE job: the § 2832 deadline (class .deadline).
 *   Nothing else on the site uses it, and nothing anywhere is orange.
 * Contrast: every text token below clears WCAG AA (4.5:1) on --bg and --panel
 * in both themes; checked in Chrome at build, see tests/test_site.py for the
 * arithmetic that keeps it that way.
