Small joys: Quote of the Day + Word of the Day engines

- quote.py: curated public-domain quote pool (16 seeded, admin-grows), deterministic daily
  pick, lazy AI "what it means" explainer of the real quote (cached). No LLM-invented quotes.
- wotd.py: LLM proposes positive words → validated/enriched against dictionaryapi.dev (real
  definition, IPA, examples, audio) → audio clip cached to our origin (TTS fallback) →
  deterministic daily pick. Tops the pool up toward 30/day.
- db.py: quote_pool/daily_quote + wotd_pool/daily_wotd tables.
- api.py: /api/quote/today, /api/word/today, /api/word/audio/{word} (GET+HEAD).
- cli.py: cycle steps for both (under --no-joys), shared LLM client.
- tests: test_quote.py (6) + test_wotd.py (5). 393 backend tests green.
