+### Documentation (#612)
+
+- Normalize docs headings and Sphinx module directives to fix anchor and index generation issues.
+- Tweak Sphinx type-hints configuration to avoid RST indentation conflicts and suppress forward-reference warnings.
+- Refresh docstrings and cross-references (pane/window APIs, environment helpers, pytest plugin) for clearer return types and stable anchors.
+- Fix incorrect return type annotations for `capture_pane()` and `display_message()` methods
+  (changed from `str | list[str]` to `list[str]` - the methods always return a list).
