Guided setup for the ProjectionLab Plugin API key.

Two-step flow:

1. Call with no args — returns instructions and a browser script that extracts, stores, and validates the key entirely in the browser.

2. Call with validationResult — confirms the key is valid and setup is complete.

The API key NEVER leaves the browser. The extractScript reads it from the DOM, stores it in sessionStorage, and validates it — all client-side. The only value that comes back to the conversation is a success/failure boolean.

The extractScript should be executed in the browser via the Playwright or chrome devtools MCP.

Returns a JavaScript string that exports all ProjectionLab data via the Plugin API. Execute this script in the browser using the Playwright or chrome devtools MCP.

The script reads the API key from sessionStorage, set during pl_setup. If the browser tab was closed since setup, run pl_setup again first.

Save ProjectionLab export data as a local snapshot file. Pass the data you got from running the pl_export script in the browser. API keys are redacted before writing.

List all saved local snapshots, sorted newest first. Returns filename, path, creation time, and size.

Read a local snapshot file and return JavaScript strings to restore the data via the Plugin API. Execute each script in the browser using the Playwright or chrome devtools MCP.

The scripts read the API key from sessionStorage, set during pl_setup. If the browser tab was closed since setup, run pl_setup again first.

Important: take a snapshot of the current state BEFORE restoring (run pl_export in the browser, then call pl_snapshot with the result).
