  telemetry.css — TELEMETRY panel
  Inherits design tokens from main.css (--font-*, --size-*, --sp-*, --surface, --border, etc.)
  Type rules: labels/summary/section titles → --font-ui; technical row values → --font-mono; min size → --size-sm.
  --telemetry-amber for elevated signal (defined in main.css :root). Red (critical) uses --warn.
