Key corrections from codebase analysis:
- Use `uv add chainlit` (not requirements.txt) — project already uses uv+pyproject.toml
- Remove .env.example task — file already exists with full config
- Add task to extend src/llm.py with stream_complete() using litellm streaming
instead of calling Anthropic SDK directly
- Reuse existing src/ modules directly in chat_app.py:
Config, KnowledgeBase, ConversationStore, AdminNotifier, prompts.py
- chat_app.py lives at project root (parallel to main.py), not in a new app/ dir
- Parse LLM response with existing _parse_llm_response logic from core.py
- Session state stored in cl.user_session, keyed by Chainlit session ID

Selects Chainlit as the chat UI library (AI-native, Python, handles
WebSocket/streaming/session out of the box). Establishes Python as the
project language. Documents accessibility gap mitigations (ARIA live
regions, focus management, reduced-motion, contrast overrides). Defines
project layout and Chainlit configuration.

Defines why the web chat is being built now, what changes (chat-interface
capability moving from spec to implementation), and adds accessibility as
a first-class requirement (WCAG 2.1 AA, keyboard nav, ARIA live regions).

Replace thread-ID-based conversation matching with email-address-based
matching for more reliable conversation continuity. Key changes:
- One conversation per email address (simpler model)
- No data expiration (conversations persist indefinitely)
- Post-completion support (questions and registration updates)
- Versioned storage for registration updates (audit trail)
- Admin notifications for registration changes
This addresses the gap where parents sending new emails (instead of
replying) would lose their registration progress.

Define complete non-technical scope for replacing Google Forms registration
with an AI-powered conversational agent. Includes:
- Registration data requirements (13 fields with validation rules)
- Knowledge base content (fees, regulations, schedule, FAQ from official PDFs)
- Conversation flow design with bilingual support (German/English)
- Agent personality guidelines (warm & friendly tone)
- Admin notification routing by playgroup type
- Email reminder system for incomplete registrations
- Data export formats (CSV/JSON)
- Channel configuration (email + chat)
- Release priorities (MVP scope defined)
