+   * Handles clicks on the editor wrapper's padding area.
+   *
+   * The editor wrapper has generous bottom padding (`pb-[60vh]`) so that
+   * users can scroll content above the fold. Clicking in this padding zone
+   * does not naturally focus the editor because the click target is outside
+   * the `.bn-editor` contenteditable region. This callback detects such
+   * clicks and programmatically focuses the editor with the cursor placed
+   * at the end of the last block.
+   *
+   * Early-return guards:
+   * 1. **Locked mode** – when the editor is read-only (`locked` is `true`),
+   *    the callback is a no-op so that clicking the padding area does not
+   *    steal focus or move the cursor.
+   * 2. **Inside `.bn-editor`** – if the click originated inside the
+   *    contenteditable region (including any descendant elements), the
+   *    callback returns early and lets the default browser behaviour handle
+   *    focus normally.
+   *
+   * @param e - The React mouse event from the wrapper `<div>`.
