Search results (FTS5 + Ollama embeddings) are shown immediately at no
cost. AI synthesis via Claude is behind a "Synthesize" button that the
user must explicitly click. Results are cached permanently so repeat
visitors never trigger API calls.
- Split ask into search_only() (free) and ask() (paid, cached)
- GET /ask now uses search_only — no Claude tokens spent
- POST /api/ask/synthesize triggers Claude (Haiku, ~$0.001)
- Cached answers shown with "cached" badge, no re-generation
- Template shows sources immediately + optional synthesize button
