/* Shared public-site footer. Source markup: static/partials/site-footer.html,
 * stamped into every public page by scripts/stamp_site_footer.py (edit the
 * partial, never a page copy — CI fails if a page drifts).
 *
 * Pages use several unrelated design systems (some dark-only, some light-only,
 * some token-driven), so this sheet owns NO colours of its own: everything is
 * derived from the host page's text colour via currentColor. That keeps it
 * legible on any background and in both themes with zero per-page overrides.
 * Selectors are class-scoped (.sf …) so page-level `footer`, `a`, `ul`, `h2`
 * rules cannot leak in, and it is a <div role="contentinfo"> for the same reason.
