/* Site chrome: header, product subnav, footer. One file, every page.
   The markup comes from ~/Obsidian/automation/ukkometa-weekly/chrome/chrome.mjs
   and is written into each page by sync-chrome.mjs; the weekly chrome-drift
   check fails when a page carries anything else. Tokens are scoped here so
   the chrome looks the same on pages whose own stylesheet defines different
   variables (the product pages carry their own :root). */
