1//! The input hero collage for the README, mirroring the C sparcli demo in a
2//! slim form: a titled hero panel and a balanced multi-column dashboard of
3//! statically rendered prompt frames (no boxes/hints, default theme).
4//!
5//! `cargo run --example prompt-readme`
6//!
7//! Each prompt's frame is produced by its `frame()` method (no TTY, no
8//! interaction); columns are stacked with `vstack` and joined with `Columns`.
9//! The fuzzy column is composed directly so the example needs no extra
10//! features.
