//! Pure HTTP transport construction
//!
//! Receives a fully-composed `HeaderMap` and timeout values, then builds a
//! `reqwest::Client`. This module has no knowledge of credentials, auth
//! strategies, or provider-specific behavior.

use crate::{ProviderError, ProviderResult};
use reqwest::Client;
use std::time::Duration;

/// Build a `reqwest::Client` from finalized headers and timeouts.
///
/// Fails fast on invalid header names or values so misconfiguration is caught
/// at client construction rather than surfacing as an opaque transport error
/// on first request.

    headers: reqwest::header::HeaderMap,
