+# Configurable Views Pane
+
+Standalone Drupal module that provides one block plugin for Page Manager / Panels variants:
+
+- Plugin ID: `booking_configurable_views_pane`
+- Form fields: `view_id`, `display_id`, `arguments`
+
+It lets editors set view target and contextual arguments per block instance, similar to legacy Drupal 7 pane behavior.
+
+## Install
+
+1. Place this module at:
+   `web/modules/custom/configurable_views_pane`
+2. Enable module:
+   `drush en configurable_views_pane -y`
+3. Rebuild cache:
+   `drush cr`
+
+## Use in Page Manager
+
+Add block **Configurable Views Pane** and set:
+
+- **View ID**: e.g. `audio_resource_embedded_player`
+- **Display ID**: e.g. `default` or `block_1`
+- **Contextual arguments**: e.g. `1770` (comma/pipe/newline separated)
+
+## Notes
+
+- This module intentionally keeps plugin id `booking_configurable_views_pane` for compatibility with any existing block config already using that id.
