   Site sidebar — expandable navigation rail
   (interaction modeled after dribbble.com/shots/26211061)

   Self-contained and theme-agnostic: every color reads from the site's
   existing CSS variables (with fallbacks), so it re-skins itself with
   the white/terminal/vscode toggle automatically. Include on every page
   alongside assets/styles.css.
