   Storefront theme — Basic Custom E-Commerce
   ---------------------------------------------------------------------------
   Loaded after bootstrap.min.css on the STOREFRONT ONLY. The admin panel keeps
   app.css (AdminLTE + dashboard tiles); the two never share a stylesheet, so a
   change to the shop cannot reach back into the admin screens.

   No build step, no CDN, no webfont (spec §5, §6, §30). The display face is a
   system serif — universally installed, zero bytes over the wire, and it gives
   the shop a voice that a stock Bootstrap sans does not.
