+10. **Streak UI**: small flame + count in the top bar, "+1 🔥" on the Session summary, tap for a panel with
+    current/longest Streak and a month calendar. No full-screen celebrations or milestones in v1.
+11. **Streak Freezes** are in v1. **Grace Hour** 00:00–01:00 counts for the previous day unless that
+    day is already done.
+12. **Reminders**: two adjustable daily Reminders (19:00 and late night), skipped when the day is done.
+    A Settings screen hosts them.
+13. **Session summary**: duration, Exercises, Set Logs and the Streak line.
+14. **No UI prototype**: the Streak is built directly in the app.
+15. **Build order**: setup/data/designs → Library → Plan editor → Player + summary → History, Streak,
+    Reminders. Commit and push after each stage; check in after stages 1 and 4.
