/* ============================================================================
   Shared site chrome — one Geneva, everywhere.
   The procedural skyline (Salève/Jura, St-Pierre, Lac Léman, Jet d'Eau) used to
   be painted per-column on the home page only, which put a hard vertical seam
   at the sidebar edge. It is now a single fixed full-viewport layer behind the
   content of every first-party page, animated on the home page and drawn once
   elsewhere. chrome.js injects the canvas and, where a page has no theme
   control of its own, a floating light/dark toggle.
