   360 TELECOM — Design tokens
   Direction: a night-network control room. Deep signal-navy canvas, a live
   radar/coverage-ping animation standing in for "the network is alive",
   cyan/blue signal light as the accent, amber for pending states (SIM-gold),
   emerald for money/success. Monospace for anything numeric (prices, phone
   numbers, order IDs) so the interface reads like real telecom tooling.
