How this trains you (deliberate practice):
Path 1 encodes first — each lesson teaches a concept in one screen, then makes you retrieve it
immediately. Path 2 is pure retrieval — interleaved drills with spaced repetition (SM-2-style
scheduling; misses return in minutes, wins stretch to weeks). Misses on any drill or lesson check
push the linked concept card to the top of your flashcard queue — mistakes are fuel, not shame.
