/* ============================================================
   OpenBridge theme. Direction: tech, re-tuned light-first for a
   clean SaaS surface (the brief pins a light look; dark also ships).
   Subject: a suspension bridge at dawn over a river, the signal
   lights on its pylons, cables, deck, a usage meter.
   Load after foundation.css. Dark remap sits under @media screen.
   Check: python3 check_contrast.py theme.css
