/* Esta dashboard styles — hand-written fallback (TDD 010: vendored Pico/htmx unavailable in the
 * build sandbox, so the app ships this and degrades to plain HTML forms; nothing functional depends
 * on htmx). Tokens are the validated dataviz reference palette: magnitude bars use one blue hue;
 * status colors (good/warning/serious/critical) are reserved for health/queue/message status and
 * always pair with an icon + text label, never colour alone. Light + dark are both selected. */
