The security update is not active at this exact head. The PPTX manifest declares DOMPurify 3.4.16, but the workspace override still forces 3.4.15 and the actual installed sanitizer resolves to 3.4.15.

Please align the affected direct manifests, override and lockfile, then verify the physically installed sanitizer and a packed consumer that does not inherit workspace overrides. These checks and the real before/after sanitization controls are completed in draft #337 at 50d4542d4c0e40b2854b5183cd1f769f497737a1; its full remote CI passed. This original head must not be approved as a completed security fix.

Superseded by the coherent DOMPurify 3.4.16 upgrade merged in #343 (eb84220) and preserved in #350 (5ebaaa3).

I checked the complete diff: this PR only changes the PPTX dependency declaration from 3.4.15 to 3.4.16. Current main has that declaration, the workspace override, and the lockfile aligned at 3.4.16, and #350's full public CI passed. The declaration/lockfile inconsistency identified in the change request remains valid for this unchanged head.

Closing as superseded; the existing change request remains part of the review history.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
