/* =========================================================
   HYTEK TELESYSTEMS — Design System
   Concept: "The Switchboard" — an enterprise telephony/network
   partner's site styled like a line directory: deep switchboard
   navy, a live-signal teal, and an amber "line active" accent.
   Numbered "EXT" style markers are used because the business
   itself is organized around lines/extensions — not decoration.
