   Markup: components/site-footer.js   Avatar: /js/site-footer.js
   Values mirror the sproutgoodhabits.com landing footer. Colours resolve
   through the page's theme tokens when present (docs.css `--docs-*`, then
   sprout-tokens.css `--theme-*`) and fall back to the landing-page hexes, so
   the footer matches its page in light and dark mode everywhere.
