/*
 * Shared site footer — single source of truth.
 *
 * Loaded by every public page (landing, leaderboard, map, guide) via
 * `<link rel="stylesheet" href="/footer.css">`. The markup is injected from
 * `partials/footer.html` (Vite transformIndexHtml + gen_guide), so neither
 * markup nor styling is duplicated per page.
 *
 * Rules are deliberately SELF-CONTAINED: explicit font-family, line-height and
 * margins so the footer renders identically regardless of the host page's
 * global styles (the landing app stylesheet vs the static site-pages.css set
 * inherit different body line-heights and `li`/`a:hover` rules — this file
 * neutralises all of that). Relies only on the shared CSS custom properties
 * (--accent, --text-dim, --panel-border) that both stylesheets define.
