Tools

Browsers and platform reach — chromeless, user-browser, platform, recorder.

Tools give an element hands in the wider world: `chromeless` is the headless browser substrate, `user-browser` drives a real user session, `platform` exposes the platform's own capabilities, and `recorder` captures a session for replay. Reach for a tool when an operation needs to *act on something external* — scrape a page, fill a form, automate a UI — rather than compute over data it already holds.
