Build the canonical `/dashboard/` route for the Crest Alpha one-shot benchmark catalog as a single-file control-room artifact.

Brief:
- Create a dense grid-operations dashboard called `Crest Alpha Grid Watch`.
- The interface should feel like a real dispatch room managing an evening load ramp, tight fast reserve, and weather pressure around the Cook Link corridor.
- Keep the copy tight, specific, and operational. No generic analytics-board language.

Panel plan:
- Sticky mission header with live mode, reserve posture, active filter, saved views, and shortcut access.
- Network pulse panel with demand, reserve margin, frequency, spot price, and a live load-history chart.
- Supply stack panel showing hydro, wind, gas, battery, solar, and import contribution with dispatch deltas.
- Ramp plan timeline panel with upcoming operator actions, hold points, and risk markers across the next two hours.
- Alert queue with severity filters, acknowledgement state, owner, system, and next action.
- Region strip showing North Chain, Waikato, Cook Link, Central Hydro, South Wind, and Battery Ring health cards.
- Transmission sketch panel that visualises the stressed network and highlights the selected focus area.
- Decision log panel with concise operator notes tied to state changes.
- Incident detail panel for the selected alert or subsystem with impact, cause, owner, and response step.

Interaction model:
- Support keyboard shortcuts for help, pause/resume, cycling filters, cycling saved views, acknowledging the selected alert, and cycling focus regions.
- Support mouse and touch interaction for alert selection, saved-view switches, region focus changes, and acknowledgement.
- Persist active filter, selected alert, selected region, selected saved view, paused state, and acknowledged alerts in local storage.
- Simulate believable live-state drift locally with no external APIs. Metrics should tighten, recover, or escalate based on reserve, storm pressure, and intertie stress.

Visual direction:
- Dark industrial control-room palette with graphite, steel blue, acid lime, amber, and fault red.
- Strong hierarchy, hard-edged panels, subtle scanline atmosphere, and restrained motion that feels purposeful rather than decorative.
- Responsive layout that turns into a deliberate stacked control deck on mobile, with the top status bar remaining useful.

Quality bar:
- The dashboard must feel operational and decision-oriented.
- Alerts need concrete causes, owners, and actions.
- The simulated system should create tension without noise.
