/* Site footer — the ONE footer stylesheet, loaded by every page (main site
   and blog). Scoped tokens on .footer keep it identical regardless of each
   page's own palette. Every descendant selector is prefixed with ".footer "
   so page-level rules (e.g. body.article-page p / a) can never leak in.
   Blog pages additionally set margin-bottom: 0 (no trailing frame padding). */
