//! Context-window and max-output-token estimates for Bedrock models.
//!
//! *Context-window* estimates delegate to the canonical
//! [`crate::provider::limits::context_window_for_model`] so a single map
//! covers all providers.  *Max-output* estimates are Bedrock-specific
//! (they vary by inference-profile, not by model family) and live here.
//!
//! # Examples
//!
//! ```rust
//! use codetether_agent::provider::bedrock::{estimate_context_window, estimate_max_output};
//!
//! assert_eq!(estimate_context_window("us.anthropic.claude-opus-4-7"), 1_000_000);
//! assert_eq!(estimate_max_output("us.anthropic.claude-opus-4-7"), 128_000);
//! assert_eq!(estimate_context_window("amazon.nova-lite-v1:0"), 300_000);
//! ```
