Overlay editor

The Overlays view edits HTML, CSS, and JavaScript independently. Each source tab shows line numbers and a small completion picker containing literal starter snippets. Selecting a completion only inserts text into the active draft; it does not execute or evaluate the snippet in the client.

Draft changes are cached locally and autosaved to the server after the debounce period. The live preview uses a sandboxed iframe. Publishing is a separate explicit action that changes the OBS browser-source output; saving a draft does not publish it. Diagnostics remain available through the warning indicator, and the server applies the authoritative size, slug, and browser-source security checks.
