## Models

The LLM defaults to `google/gemini-3.8-flash` at low reasoning effort, with
`google/gemini-3.5-flash-lite` for proposing a direct address and typing field text.
Override with `FASTBROWSE_LLM_MODEL` (every purpose), `FASTBROWSE_LLM_MODEL_<PURPOSE>` (`PLAN`,
`READ`, `FIELD_TEXT`, `SHORTCUT`, `RECOVER`, `COMPOSE`, `VERIFY`) and `FASTBROWSE_LLM_REASONING`
(`low`, `medium`, `high`).
