1//! LLM provider selection and integration.
2//!
3//! Domain types (traits, provider structs) are defined in `gestura-core-llm` and
4//! re-exported here.  This module adds the core-owned [`select_provider`]
5//! function which bridges [`crate::config::AppConfig`] to concrete provider
6//! instances.
