- content-editor.js: extract the /save handler to scripts/cms-save.js
- cms-logo-page.js: inline the ~280-line canvas editor script to
scripts/cms-logo-client.js (page is now the HTML/CSS shell only)
- cms-editor-client.js: move the keyboard-shortcut section to
scripts/cms-editor-shortcuts.js, inlined after the main client
All modules now under the hard limit; full pre-deploy suite green.
