/* CSV Manager - wp-admin styling.
 *
 * Visual language follows wp-admin conventions (form-table, button-primary,

 * scrollable wizard rather than three separate page loads.
 *
 * Colour palette mirrors the rest of the plugin:
 *   primary   var(--w2dc-primary, #2271b1)
 *   ok-green  #16a34a / bg #dcfce7
 *   err-red   #dc2626 / bg #fee2e2
 *   warn-amb  #d97706 / bg #fef3c7
 *   muted     #6b7280
