[Phase 4.1] Study Tools: Worksheet Generator & Flashcards

[robinson]

Goal

Add dedicated study-tool surfaces — worksheet generation and spaced-repetition
flashcards — as first-class features alongside the chat interface.

Worksheet Generator

• Prompt the AI to generate a printable/exportable worksheet for a given topic.
• Output: PDF-ready HTML; subjects, difficulty level, question count configurable.
• Integration: calls existing eule-core inference API.

Flashcard System

• Student or AI can create flashcard decks from chat sessions.
• Spaced-repetition scheduling (SM-2 algorithm).
• Deck management: create, edit, archive.
• Study session UI: flip animation, self-rate (easy / medium / hard).

Acceptance Criteria

• Worksheet export produces valid PDF-printable HTML.
• Flashcard due dates follow SM-2 scheduling.
• Study session plays through due cards and updates intervals on rating.
• Decks persist in SQLite.
