save_to_html() exports rendered a blank page: kepler.gl's availableThemeSelector in <=3.3.0-alpha.6 returns the theme value unchanged when no theme prop is provided, and the standalone template mounts <KeplerGl> without one, so bottomWidgetSelector crashed reading theme.sidePanel.margin.left. The unknown-theme fallback to the default dark theme landed in v3.3.0-alpha.7 (a0bee76, #3620); verified headless Chrome renders arcs, points and basemap correctly with 3.3.0-alpha.8. Also bumps pyproject to 0.4.0rc5 so a new prerelease can be published with the fixed template. Co-Authored-By: Claude Code <noreply@anthropic.com>

Pull request overview
This PR updates the Python Jupyter bindings’ standalone HTML export template to load a newer kepler.gl UMD bundle from unpkg, addressing a blank-page crash in save_to_html() exports by picking up upstream theme-handling fixes.
Changes:
- Bump the pinned kepler.gl CDN UMD/CSS version in the standalone export template to
3.3.0-alpha.8. - Update Python tests that assert the embedded CDN URLs.
- Bump the Python package prerelease version to
0.4.0rc5.

The 0.4.0rc5 bump updated pyproject.toml but not keplergl/_version.py, so keplergl.__version__ reported 0.4.0rc4 at runtime. Co-Authored-By: Claude Code <noreply@anthropic.com>

Publishing still needs to be done manually: after merge, run the Build and Publish KeplerGL Python Package workflow via
workflow_dispatch(prerelease checked) → PyPI0.4.0rc5. Users on the editable/source install are fixed immediately; PyPI users need the release.🤖 Generated with Claude Code
