notebooks had "theme": true, so Traefik's inject-fhirworx middleware
added assets/css/inject.css — the universal sheet written for Grafana,
Trino, Prometheus and RustFS (its own header says so) — on top of
marimo's dedicated theme (marimo.css via custom_css). Its blanket rules
([class*="primary"] { background: navy }, [class*="button"]:hover …)
painted every home-page row navy (marimo rows carry hover:text-primary)
and flattened the shutdown dialog so Shutdown looked exactly like
Cancel. marimo now gets only its own theme.
