What's real here, what isn't yet
The breathing timer, checklist, and session history above are real, functioning tools — all state persists in your browser between visits. What's not built yet: any actual AI-personalized coaching, biometric input (heart-rate, HRV), or cross-device sync (this history lives only in this browser, same honest limitation as golflink.cc's ledger). This page will be extended honestly as those pieces become real, not described as if they already exist.
