1//! Centralized default AI model constants for all providers.
2//!
3//! This module provides a single source of truth for default model identifiers
4//! across OpenAI, Anthropic, Grok, Gemini, and Ollama providers. These constants
5//! are used as default values in `AppConfig` structs (e.g. serde defaults).
6//!
7//! ## Model Selection Precedence
8//!
9//! The system uses the following precedence for model selection:
10//! 1. **User configuration** (from `~/.gestura/config.yaml`)
11//! 2. **API discovery** (dynamic model lists from provider APIs)
12//!
13//! There are no static fallback lists — if the API is unreachable or no API key
14//! is configured, the model list is empty and the UI communicates this to the user.
