/* ============================================================
   VidaRent — glass

   The interface over a polished-concrete floor: an off-white page
   with the soft light of a showroom on it, frosted panes for the
   cards, a smoked-glass sidebar along the window's edge, and each
   section's glass-tile icon. Loaded last, it changes surfaces — colour,
   translucency, corners, shadow — and never the layout of a screen.

   Real blur (backdrop-filter) only where something passes beneath:
   the sidebar, the top bar, the fleet's sticky filter, popovers and
   toasts. Cards are translucent over a still page, which looks the
   same and costs nothing on a phone.
