//! Built-in 2026-Q1 list-price rate table.
//!
//! Owns the literal-rate constructor that populates [`super::PriceTable`]
//! with the providers shipped by klieo. Kept in a sibling module so the
//! `Rates` + `PriceTable` types in [`super`] do not balloon with literal
//! pricing data that changes on a separate cadence from the type-level
//! lookup logic.
//!
//! See the parent [`crate::pricing`] module docs for upstream pricing URLs
//! and the rate-source refresh cadence.
