## Run

Open `index.html` directly in a modern browser. No local server, build step, package manager, or network access is required.

## Controls

- Use the facility and date-range selectors to update the live-data view.
- Use the **Data view** buttons to exercise populated, loading, empty, and data-issue states.
- Use the sidebar chevron on desktop and the Menu button on mobile to toggle navigation.
- Standard buttons, links, and form controls are keyboard operable; Escape closes the mobile navigation.

## Verification performed

- `node --check script.js` syntax validation.
- Required-file inventory and external-reference scan.
- Source-level interaction audit for populated/loading/empty/error controls, state templates, facility and date-range handlers, sidebar controls, Escape handling, and semantic labels.
- Source-level responsive audit for desktop/tablet/mobile breakpoints, table-local overflow containment, focus-visible styles, and reduced-motion rules.
- Browser verification was attempted with the in-app browser. Its security policy blocks the local `file://` page, so actual rendered mouse/keyboard/viewport inspection was not possible in this environment.

## Verification results

- PASS: JavaScript syntax, required files, no external assets/dependencies, all required view-state controls/templates, selector handlers, sidebar code, labels, focus rules, responsive breakpoints, reduced-motion rules, local table overflow treatment, and non-visible identity markers.
- Not executed: live rendered visual checks at desktop/tablet/mobile widths, actual mouse/keyboard interaction, rendered chart/table/page overflow, and rendered focus-ring inspection. The local browser policy blocked the only approved browser surface from opening `file://` content.

## Known limitations

- The dashboard uses deterministic sample operational data; it does not connect to a live logistics system.
- For narrow layouts, the facility table intentionally uses an internal horizontal scroll container to preserve its columns.
- Browser-rendered acceptance checks remain an environment limitation because local `file://` navigation is blocked by the available browser policy.
