/* =============================================================================
 * docs.css — Vivetra Docs (docs.vivetra.vet) — the whole site's stylesheet
 * Version: 1.0
 * Last Updated: 2026-11-04
 *
 * FILE CONTEXT:
 *   LOADED BY: every page tools/docs/build.php writes, as /assets/docs.css?v=
 *              <docs_version>. No other stylesheet, no web fonts, no CDN.
 *
 * PROJECT: Vivetra (project v0.265.4.5) — docs.vivetra.vet pipeline
 * FILES:   assets/docs.css  (this file — layout, prose, search palette)
 *          assets/docs.js   (search palette, role filter, TOC spy, copy links)
 *          tools/docs/build.php (emits the markup these rules style)
 *
 * ARCHITECTURE:
 *   - Colour tokens + system font stack COPIED (values only) from
 *     sites/vivetra-vet/css/style.css — never linked (cross-site rule).
 *   - Light-first tokens with a prefers-color-scheme: dark override.
 *   - Mobile-first; breakpoints 900px (sidebar becomes a column) and 1180px
 *     (right-hand TOC rail appears). Nothing may scroll the page sideways at
 *     375px: tables and code scroll inside their own box.
 *   - CSP style-src 'self': no inline styles anywhere, so state is classes
 *     and attributes only ([hidden], aria-current, aria-pressed, .nav-open).
 *
 * CHANGE LOG:
 * v1.0  2026-11-04  Claude  Initial docs site stylesheet.
