## Governing Mathematical Formulation & Units
- Formula: `Lesson Completion Progress = Σ_{i=1..6} Completed_Lesson_i / 6; Spaced Recall Score = Correct Prompts / Total Prompts in Lesson Set`
- Units: 6 structured sample lessons spanning introductory A1–B1 communicative patterns; local learning passport stored in browser JSON.

## Reproducible Worked Example
Sample Lesson Contrast (A1 Present vs. Near Future — 'aller + infinitive'): Compares French sentence structure ('Je vais étudier ce soir') with English ('I am going to study tonight') and Bangla ('আমি আজ রাতে পড়তে যাচ্ছি'), followed by an interactive fill-in-the-blank check and local passport checkpoint.
