/* Shared site footer for the plain static HTML pages (public/*.html).
 *
 * These pages are hand-written and do NOT load the Tailwind bundle, so the
 * canonical footer (src/components/SiteFooterMarkup.jsx) can't be reused
 * directly. This stylesheet reproduces that footer's "Direction 2B / Corporate
 * Dark" look with plain CSS, and scripts/partials/footer.html supplies the
 * matching markup. scripts/inject-footer.mjs injects the partial into every
 * static page and ensures this stylesheet is linked, so the static footers
 * cannot drift from the React one.
 *
 * Tokens mirror src/index.css @theme:
 *   --color-dark-800: #0B1120  (footer background)
 *   --color-accent:   #3B82F6
 *   --color-on-dark:  #F1F5F9
 *   --color-on-dark-muted: #94A3B8
