/* Fleet monitor, for docs/fleet-monitoring.md.
 *
 * Every colour is a Material for MkDocs variable rather than a literal, so the page
 * follows the site's light/dark toggle instead of having a second opinion about it.
 * The alert bands are the exception: red, amber and green have to mean the same thing
 * here as they do on the device's own dashboard, so they are stated once and reused.
 *
 * Prefixed .fleet- throughout. This stylesheet is loaded on every page of the site
 * (see the note in mkdocs.yml about why a per-page <link> cannot work), so a bare
 * .card or .pill here would restyle the theme.
