/* ============================================================
   Antenna Demo — wire.css
   The wire-antenna module (wire.js): the Dipole, and the Monopole in
   phase 2. Scoped under .ant-wire, the family class makeWireAntenna puts
   on both roots; .ant-ground (the monopole) can override any of it.
   The module's state classes (mode-shape, style-simple, tab-rx) sit on
   its own root, never on <body>.
