   Simple Apps — shared design tokens + base components.
   Extracted verbatim from the proven Image Viewer landing page so every app in
   the catalog shares one design system. Per-app pages add only their own accent
   tweaks and section-specific styles on top of this.

   The build inlines this via  <!-- @@include partials/head-common.html -->
   (which <link>s it) — see build/build-web.js.
