sparcli 0.3.0

//! A gallery of every static output widget. Run with
//! `cargo run --example output_gallery --features markup,fuzzy,pager`.
//!
//! Everything here renders to a fixed frame, so the output is deterministic
//! and pipe-friendly (`| cat`, `> file`, or `NO_COLOR=1` yield plain text).
//! Time-based widgets (spinner animation, progress, multi-progress, live,
//! pager) live in the `output_dynamic` example.
