/* components.css — shared components that must exist on EVERY page.
   Loaded from _components/partials/head-tail.html (single-sourced), after tokens.css and
   before theme.css. Exists because nav styling is duplicated across solutions.css AND 9
   inline <style> blocks — putting shared component CSS in either would mean 10 edits and
   guaranteed drift. Everything here uses design tokens, so both themes work with no patch. */

   Canonical logo: https://appd-assets.pages.dev/logo.gif (Ankit's instruction). Width/height are
   set on the tag so the nav never shifts while it loads, and the source is square so
   object-fit keeps it undistorted. NOTE: the asset is ~953 KB and animated, and its host sends
   Cache-Control: max-age=0, must-revalidate — so it re-checks on every page view. */
