HTML Preview
Live
Pane type
Preview web pages with CSP sandboxing. Render local HTML safely inside the workspace, updating as the file changes on disk.
What it shows
Point the pane at an .html file and it renders the page in a Content-Security-Policy-sandboxed view. Unlike the Browser pane, which loads arbitrary URLs in a full WKWebView, HTML Preview is scoped to local files with a tightened CSP so untrusted markup can be inspected without granting it network or script reach.
Keyboard
Open via ⌘K → type the pane name. Close with ⌘W. Focus with ⌘+digit (the pane's position on the canvas).
