Field notes
The integration walkthrough divides the work between a script tag, an agent prompt, and a local test command. The agent is meant to choose a genre-specific pattern and connect four hooks; the example test reports checks across two browser sessions. Joinable describes its SDK as roughly 21 KB gzipped and async, and names Etheria's Turbo Rally as its first customer.
