## Run

Open `index.html` directly in a modern browser. No web server, build step, package manager, network request, or installed dependency is needed.

## Verification performed

- Ran `node --check script.js` after implementation and after the final responsive correction.
- Ran a 20-assertion local static acceptance check covering the exact title and benchmark comment; populated, loading, empty, and error templates; state-render paths; facility and date-range handlers; mouse and keyboard control handlers; sidebar and mobile-navigation handlers; labels and live-region ARIA; focus styling; chart, table, and page overflow containment; responsive breakpoints; mobile collapsed-sidebar width; reduced motion; offline assets; and the isolated file set.
- Confirmed the assigned directory inventory with `rg --files`: exactly `index.html`, `styles.css`, `script.js`, and `RUN.md`.
- Performed source-level interaction review of state selection, refresh/retry flow, facility/date selection, sidebar collapse/expand, mobile navigation, Escape behavior, and range-specific chart labels.
- Attempted browser-based visual acceptance at desktop, tablet, and mobile widths. The local `file://` URL was blocked by the available browser-testing environment, so no browser-policy workaround was used.

## Verification results

- JavaScript syntax checks passed.
- Static acceptance checks passed: 20/20.
- The initial range selector review revealed that a multi-day selection retained intraday chart labels; this was corrected so 7-day and 30-day selections render their own series, labels, and explanatory note.
- A mobile sidebar review revealed that labels collapsed while width remained expanded; this was corrected with a 68px mobile collapsed width.
- No network-dependent assets or data calls are present.
- Every generated file is inside the exact assigned directory.

## Known limitations

- The dashboard uses deterministic local sample data rather than a live logistics data source, so refresh/retry demonstrate the interaction without contacting a service.
- Notification, profile, report, settings, and "view all" controls intentionally do not navigate to separate pages in this standalone single-page implementation.
- Visual browser inspection at desktop, tablet, and mobile widths could not be completed because the available browser-testing environment blocks local `file://` pages. Static responsive, overflow, focus, and reduced-motion checks passed; open `index.html` locally for a final visual smoke test if required.
