//! ai-usagebar library — shared core for the Waybar widget and TUI binaries.
//!
//! The crate is organized by concern, not by binary:
//! - low-level primitives (`cache`, `countdown`, `pacing`, `pango`, `theme`)
//! - the vendor abstraction (`vendor`, `vendors::*`, `usage`)
//! - bin-specific composition (`widget`, `tui`) which lives next to its binary
//!
//! The two binaries (`ai-usagebar` and `ai-usagebar-tui`) are thin: they parse
//! CLI args, instantiate vendors, and hand off to a renderer in this crate.
