Review

Changes look correct. Three things in this PR:

1. type = 'module' on GO-CAM viz script — The production bundle is an .esm.js file, so it must be loaded with type = 'module'. Without this, browsers would reject the ESM import/export syntax in the bundle. Clear bug fix.

2. genomefeatures bump — Pin moves to a new commit (alias-normalization fix). Lock file is consistent with package.json.

3. New test — Verifies the production path sets type = 'module' on the correct script element. Test properly saves/restores NODE_ENV and cleans up document.head between runs.

No issues found. The ribbon-strips and ribbon-table scripts intentionally remain classic scripts (their bundles are non-ESM .js files), so the asymmetry is correct.

LGTM.
