Recipe idea: Web browsing with Plasmate instead of Chrome

Most web browsing recipes in the cookbooks use Playwright/Chrome to fetch page content before sending it to Claude. This works but sends 50K+ tokens of HTML noise per page.

[Plasmate](https://github.com/plasmate-labs/plasmate) is an open-source browser engine that outputs semantic content, compressing pages by 10-16x. It also ships as an MCP server.

A cookbook recipe could show:
1. Install Plasmate: `pip install plasmate`
2. Fetch a page: `plasmate fetch ` -> clean JSON
3. Send the SOM to Claude (16x fewer tokens, 94% cost savings)
4. Compare the same task with raw HTML vs SOM

We have Jupyter notebooks ready if useful: https://github.com/plasmate-labs/notebooks
