/* Navbar "Infraestructura" panel (Components/Layout/InfrastructurePanel.razor).
   Dark side panel in the spirit of MetaMask's: near-black ground, dark-grey cards, hairline
   borders, light text, violet accent for the active section.

   Two modes, split at 1024px:
   - >= 1024px: the panel RESERVES space. The <html> element gets .infra-panel-open (infraPanel.js),
     the document body gives up the panel's width on the right and the fixed header follows, so the
     page is compressed to the left rather than covered.
   - <  1024px: the panel is an overlay sheet with a visible close button that respects the
     device safe areas; the page underneath is left exactly as it was.

   Global (not scoped) because it has to address <html> and elements owned by other components. */
