/* Climate Heroes shell - the shell's own pages, and the base every dashboard
   gets by linking  <link rel="stylesheet" href="/shell/shell.css">

   Colours come ONLY from the Climate Heroes design system: tokens.css is an
   exact copy of climate-heroes-design-system/css/tokens.css, imported here so
   any page linking this file gets the palette. Light theme only - there is no
   dark mode, by design (white page, blue text). test_shell.py fails if the
   copy drifts from the design folder or a page uses a colour outside it.

   The design system's components (.ch-panel, .ch-logo, .ch-meter ...) are a
   separate file: <link rel="stylesheet" href="/shell/ch/components.css">,
   and its behaviours <script src="/shell/ch/helpers.js"></script>. */
