/* ============================================================
   CyberShield — Cyber Security News Dashboard
   style.css · Cybrexa Internship · Project 04 (Capstone)

   Design Direction:
   Dark ops console aesthetic — NOT the typical near-black +
   acid-green. Instead: deep navy base (#060d1a) with a
   phosphor-amber accent (#f5a623) — the color of old
   radar screens and threat consoles. Signature element:
   the animated scan-line overlay across the whole page,
   evoking a live security operations center monitor.
   Type: Share Tech Mono for data/labels, Inter for body.
