+/**
+ * Plugin Name: Asterion — Enable Bricks publicTemplates setting
+ * /?av_enable_public_templates=1
+ *
+ * Bricks redirects /template/* URLs to the homepage when the user can't use
+ * the builder AND publicTemplates is unset. This causes "Edit with Bricks"
+ * to fail with "Invalid post type" because the builder URL (?bricks=run on
+ * the template permalink) gets redirected before reaching the builder.
+ *
+ * The fix : set publicTemplates=1 in Bricks global settings. Templates are
+ * still excluded from search results, but their permalinks resolve normally
+ * → the builder can load them.
