export-premiere

I'd like you to add a skill to Wideframe called "export-premiere".

What it should do:
Export a sequence or selects to a Premiere .prproj that opens clean, with every clip intact.

Before you run anything, ask me to confirm:
- Which sequence(s) should be exported?
- Sequence resolution and frame rate for the project?
- Destination path for the .prproj, and overwrite if it already exists?
- Bin structure for the clips, if any?

Then do the work:
1. Resolve the source sequence and confirm the output path is writable.
2. Map each clip to a project item with a correct media path.
3. Export with sequence-export-premiere at the confirmed resolution and fps.
4. Run prproj-validate to check for dangling references and orphans.
5. Run prproj-inspect and reconcile the clip count against the source.

Do not grade your own work. When the output is ready, hand it to a separate verification subagent that has its own context window. Give it the output, the choices I confirmed, and the pass criteria below. It reviews the quality, writes specific feedback, and returns PASS or FAIL.

Pass criteria:
- prproj-validate reports no dangling references or orphans.
- The clip count in the project equals the source sequence clip count.
- Sequence resolution and fps match the request.
- The file exists at the agreed path.

If it returns FAIL, apply the feedback, redo the affected work, and verify again with a new subagent. Repeat until it returns PASS, then show me the result.

Once it works, save it as a reusable skill named "export-premiere" so I can run it again by saying /export-premiere.
