/* ═══════════════════════════════════════════════════════════════
   PHILIP AKEKUDAGA — NETWORK MONITORING TERMINAL PORTFOLIO
   ═══════════════════════════════════════════════════════════════ */

/* DESIGN BRIEF
Concept: Network monitoring terminal — like SSH into a researcher's workstation
Tone: Dark ops dashboard, real tool, not a template
Typography: Space Mono (display/mono) + IBM Plex Sans (body)
Color strategy: Deep blue-black bg + cool blue accent (#4da8da) + terminal green (#38c172)
Layout signature: IDE chrome — titlebar, sidebar, tabbed content, statusbar
One memorable thing: The whole site IS a tool. You're inside Philip's system.
Anti-patterns avoided: No gradient cards, no symmetric grids, no hero+features flow,
  no rounded pills, no pastel gradients, no emoji icons, no template structure
