/* gnetfi.com -- shared look for every page.
   Drawn from the GNET Piso WiFi logo itself: its royal blue, the Wi-Fi arcs, the gold peso coin.
   Light paper background (operator's choice for this site, 2026-09-06). Same type as the GNET
   admin -- Sora for headings, IBM Plex Sans for reading -- so the two products feel like one maker.
   The one loud element is the signal lamp (.lamp): the logo's arcs, lit green when a board is
   online. Everything else stays quiet. */
