   babel · telemetry console
   ────────────────────────────────────────────────────────────────────────────
   A single-user instrument panel for the babel proxy. Design language:
     • IBM Plex Sans (UI) · IBM Plex Mono (all data, tabular-nums) ·
       Instrument Serif (wordmark + hero figures)
     • graphite canvas, one restrained teal accent, tinted status semantics
       (green healthy / amber paused / red dead) as soft-bg + saturated-fg,
       never solid blocks except the destructive badge
     • hairline cards, right slide-over detail drawer, live 1-second
       countdown ticks (data polled slowly), thin progress bars w/ time pin
   Both themes; dark-first, auto via prefers-color-scheme unless overridden.
