/*
  Admin dashboard styles. Different aesthetic from the main app — this is
  a working tool, not a marketing surface, so denser type, tabular layouts,
  no decorative serif. Matches the AMF Observability reference:
    - Deep blue-black canvas (#0b0f17)
    - Slate cards with subtle borders
    - Monospace numerics, sans-serif labels
    - Status colors are functional: green / amber / red / gray
