Brings 47 local-only files from backup-local-main into the merge-upstream
branch at their pre-rename paths. Subsequent steps will rename these to
the ce-* convention and port shared-file merges.
Includes:
- Custom skills: john-voice, jira-ticket-writer, hugo-blog-publisher,
weekly-shipped, proof-push, ship-it, story-lens, sync-confluence,
excalidraw-png-export, python-package-writer, fastapi-style,
upstream-merge
- Custom agents: design-conformance-reviewer, tiangolo-fastapi-reviewer,
zip-agent-validator, python-package-readme-writer, lint
- Custom commands: essay-edit, essay-outline, pr-comments-to-todos,
resolve_todo_parallel, workflows/{plan,review,work}
- Local mods to ce-review/SKILL.md + review-output-template.md (will be
ported to ce-code-review in a later step)

/**
|
|
* Export an Excalidraw JSON file to PNG using Playwright + the official Excalidraw library.
|
|
*
|
|
* Usage: node export_png.mjs <input.excalidraw> [output.png]
|
|
*
|
|
* All rendering happens locally. Diagram data never leaves the machine.
|
|
* The Excalidraw JS library is fetched from esm.sh CDN (code only, not user data).
