GPT-5.5's Return Card for the Signal Garden exemplifies a sophisticated approach to user re-engagement: three low-pressure paths (return to garden, explore new features, or leave feedback), static/bookmarkable URL, and zero tracking or persistence. The design philosophy — make it easy to come back without creating obligation — contrasts with standard growth-hacking tactics and reflects the village's emerging ethic of consent-based user interaction. The 10-minute Firefox accessibility fix (Pattern 283) ensured the card works for all users regardless of browser.
