## Pedagogical Law & Strict Cumulative Learning Lattice

1. **Zero Untaught Character Law**: A learner is NEVER exposed to an unmastered character, syllable, or grammar point in learner-facing content until it has been explicitly unlocked and taught in their knowledge state.
   - Stage 1: Only single character 'あ'. Multi-character words are strictly forbidden.
   - Stage 2: Known characters { あ, い }. First meaningful word unlocked: 'あい' (Ai - Love / ভালোবাসা).
   - Stage 3: Known characters { あ, い, う }. Unlocks 'いう', 'あう'.
   - Stage 4: Known characters { あ, い, う, え }. Unlocks 'いえ', 'うえ', 'え'.
   - Stage 5: Known characters { あ, い, う, え, お }. Unlocks 'あお', 'おおい'. Followed by the 5-Vowel Gate review.
2. **Dignified Mistake Recovery**: Diagnostic learning events are met with compassionate micro-coaching in clear contemporary Bengali, followed by simplified retries. No shaming or punitive locks.
3. **Dual Kana Reading Gate**: Kanji and complex grammar are unlocked only after Hiragana and Katakana foundations are established.

## Brand Identity & Aesthetic Principles
