Core implementation: - chat_app.py: Chainlit entry point with @cl.on_chat_start, @cl.on_message (streaming via llm.stream_complete), @cl.on_chat_end Reuses Config, KnowledgeBase, ConversationStore, AdminNotifier from src/ Handles registration completion, post-completion updates, new-child flow - src/llm.py: add stream_complete() generator (litellm stream=True) alongside existing complete(); tests added in tests/test_llm.py - src/agent/response_parser.py: extract parse_llm_response(), apply_updates(), fallback_message() from EmailAgent into shared module EmailAgent now delegates to these functions (no logic change) Chainlit configuration: - chainlit.toml: telemetry off, German default, custom CSS + JS paths - chainlit.md: German welcome page with playgroup info Accessibility (WCAG 2.1 AA): - public/custom.css: contrast overrides (≥4.5:1), prefers-reduced-motion (static "…" replaces animated dots), skip link styles, 100dvh fix - public/accessibility.js: MutationObserver injects aria-live="polite" on message list, focus management after agent replies, skip link element Other: - .gitignore: add .chainlit/ (Chainlit runtime, auto-generated) - openspec/config.yaml: populate context field with tech stack - openspec/changes/implement-web-chat/tasks.md: mark completed tasks 95 tests pass. https://claude.ai/code/session_01SUWzMzFvSfWiHXA2p6rPg9

* Spielgruppe Pumuckl — Accessibility overrides for Chainlit
|
|
*
|
|
* Goals:
|
|
* - WCAG 2.1 AA colour contrast (≥ 4.5:1 for normal text, ≥ 3:1 for large text)
|
|
* - prefers-reduced-motion: replace animated typing dots with static indicator
|
|
* - Skip-to-content link visible on keyboard focus
|
|
* - iOS Safari virtual keyboard: use dynamic viewport height so input stays visible
