/* ============================================================================
   Veld — the demonstration chrome
   ----------------------------------------------------------------------------
   The cursor, captions and cards the director draws over the app on
   /demo-player.html. Deliberately not in app.css: none of this is part of the
   product, and the one thing worse than a demo page is a demo page whose styles
   leak into the thing being demonstrated.

   A FILE RATHER THAN A <style> BLOCK

   Not a preference. _headers sets style-src-elem 'self' with no inline escape,
   so a <style> block in the page would be dropped by the browser in production
   and nowhere else — the page would look right locally and arrive with no
   captions, no cards and no cursor. The same goes for the director's own
   bootstrap, which is why showcase-boot.js exists rather than a <script> block.

   What the director sets from JavaScript — the cursor transform, the spotlight
   rectangle, the progress width — are element styles, which style-src-attr
   allows. That is the same allowance the tour spotlight and the portal's
   progress bars already rely on, and the reasoning is next to the policy.
