/* AI Visibility Audit. One design system, derived from this product's own direction: a cool slate
   console on warm paper, a signal green for passes and an ember for fails, system type only (no web
   fonts, no third party request). Layout rhythm: a scan bar at the top of the tool, results as a
   stack of left-barred rows, content in a measured prose column. */
