/* =============================================================================
   Quasar Glass bundle pages (quasar-glass-<slug>.html)
   -----------------------------------------------------------------------------
   The page layout is the Safiery product-page layout: the page uses the same
   markup product.html and product-story.js produce (the .pdp hero, the sticky
   .pdp-rail and the .pdp-story sections), styled by store.css. This file only
   adds what a configurable bundle needs on top of it: the configurator and its
   summary, SVG films in the standard film player, and a few bundle details.
   Classes here are .qb-* (plus product.html's own .doc-list, which lives
   inline on product.html rather than in store.css).

   Film line language shared by the Quasar Glass bundle films: solid orange for
   electrical power, dotted cyan for data (--qb-power / --qb-data).
