Create a single-file dense operations dashboard benchmark with live-state illusions, keyboard shortcuts, believable control-room data, and high information hierarchy.

## Route brief

Build `/dashboard/` as a live HTML operations room: a mission-control interface for a regional grid and logistics network under rolling stress. The screen should feel useful to an operator rather than merely decorative.

## Panel plan

- Executive command strip with current operational posture, incident count, grid load, fleet health, and response SLA.
- Main topology canvas showing hubs, routes, degraded corridors, and live pulses.
- Incident queue with severity, owner, countdown, cause, and consequence.
- Timeline of events with acknowledgement state.
- Capacity, latency, and dispatch charts that update locally without external APIs.
- Detail drawer for selected nodes or incidents.
- Operator console and shortcut overlay.

## Interaction model

- Keyboard shortcuts: `/` focus command, `?` shortcuts, `A` acknowledge selected alert, `F` cycle filter, `P` pause/resume simulation, `D` toggle density, `Esc` close overlays.
- Mouse/touch: click nodes and incidents for details, toggle filters, acknowledge alerts, pause live updates.
- Persisted state: selected filter, density mode, acknowledged alerts, and paused/live mode via localStorage.

## Visual direction

Dense but readable control-room design: dark graphite panels, strong hierarchy, amber/red stress states, cyan active telemetry, compact tables, animated SVG/canvas telemetry, and responsive mobile mode that becomes a structured operator stack.
