/* StarCode — Stylesheet */

/* The `hidden` attribute must always win. A plain class selector like
   `.anomaly-overlay { display: flex }` is author-origin and beats the UA
   stylesheet's `[hidden] { display: none }`, so any panel styled that way
   stays on screen forever, painting an opaque scrim over the whole app.
   Every panel here is toggled via `el.hidden = true/false`, so this rule
   is the correct single place to enforce it — when the attribute is
   removed the element's own display value applies again as normal. */
