Web MVP: Core Loop v1.0.0
This is the browser-based simulation of the CLI script. It focuses purely on the single-card display, clearing the screen after input, and advancing the 5-heart mastery system.
v1.0 Notes: Database simulated via JS Array. Contains first 4 patterns. Pressing 'Enter' submits the answer. Correct answers add a heart. 5 Hearts masters the card and unlocks the next locked card. Wrong answers currently have no penalty.
