+## G. Spec ↔ Config Actions
+
+Two editor actions make the injected chart theme portable (see _Live Preview → Chart theme_). Their visible home is a **Config** menu in the editor toolbar (a value-select disclosure listing both actions with a one-line description each), disabled when no snippet is active or the read-only published view is shown; the editor's right-click context menu and F1 command palette offer the same actions as expert accelerators. Both actions replace the document as a single undoable edit (⌘/Ctrl+Z restores), reformatted in the app's JSON style, and both refuse with a clear toast when the document is not a valid JSON object.

+- **Merge Chart Theme into Spec** — bakes the currently selected chart theme into the spec's own `config` block, deep-merging under any existing `config` so the spec's own keys win and the rendered result is unchanged. Use it before publishing a spec somewhere the app's theme won't follow. When the selected theme injects nothing (Stock Vega-Lite), the action explains there is nothing to merge.
+- **Extract Config from Spec** — removes the spec's `config` block and copies it to the clipboard, for cleaning baked-in styling out of a pasted spec. The clipboard copy happens **before** the removal; if the copy fails, the spec is left unchanged so the config is never lost. A spec with no config block reports that and changes nothing.
