Now 3 shared modules (zero code duplication):
- _page_editor_content.html — editor HTML (title block, slash menu, toolbar etc)
- _page_editor_scripts.html — 100% original editorState() JS (CMDS, render,
save, slash, database, share/publish, favorites, formatting, etc)
- Used by page_editor.html (full page) and page_editor_embed.html (peek iframe)
Embed page_editor_embed.html now has the exact same editor as full page.
One change to _page_editor_scripts.html updates both views.
