Genesis Widgetized Not Found & 404

Helpful content when nothing is found.
Widget content for 404 pages and empty search results in classic Genesis themes. Includes a search widget, shortcodes and optional 404 starter content.
Version 2.0.0 · WordPress ≥ 6.4 · PHP ≥ 8.0 · Genesis
The setup overview shows assigned widget counts, the empty-area fallback and individual editing links, including bbPress when its area is registered. Counts do not guarantee visible output: widget visibility rules still apply. Conflicting search-widget rules and logged-in-only visibility are explained. The new rules Only on 404 pages and Only on searches with no results are optional.
Frontend test links open normal requests in a new tab, separately from the existing Customizer previews. Also test logged out; search plugins and redirects may affect the result. Shortcodes can be copied with the button, or selected manually if clipboard access is unavailable. Widget-area shortcodes render assigned widgets, not starter content.
The optional 404 starter is off by default. When enabled and the 404 widget area is empty, it supplies a heading and explanation, plus optional search form and homepage link. Empty text fields use translated defaults. Assigned 404 widgets always take precedence; even a widget hidden by its own rule prevents the empty-area fallback. Disabling the starter restores the usual Genesis output for an empty 404 area. The real missing-page request keeps its 404 status. All settings belong to the current site.
