⊿ Streak, one lesson a day banks it. That's the whole game; extra lessons bank tasks, not days.

Freezes. Earned at day 3 and day 14. A freeze covers a missed day automatically, so life doesn't burn your streak.

⊿ Nails. Every 7-day streak earns one: a pass that opens any Pro lesson, yours forever. Bank up to 2.

Tiers. Rookie → Producer (day 7) → Top Producer (day 30). Tiers open capability and status. Never the next lesson.

Levels. High scores raise your level; higher levels hide the examples and raise the pass bar. The training wheels come off as you get good.

Free plan. 2 lessons a day. The streak only ever needs 1.
