/* Engineering Runtime Control Plane — demo portal.
 *
 * Visual system aligned with engineeringruntime.com:
 *   - Header chrome: blue → black gradient (always)
 *   - Body: white (light) or dark slate (dark), via data-theme
 *
 * Component rules remain a hand-port of the enterprise portal so the two
 * products still read as one family. When the docs site banner tokens change,
 * change `--er-banner-gradient` here too.
