1//! inline_runs — exercises the attributed-text path.
2//!
3//! One paragraph composed of styled inline runs (regular + bold +
4//! italic + colored + monospace) plus a hard break, all flowing through
5//! cosmic-text's rich-text shaping. Wrapping decisions cross run
6//! boundaries — the same way a `<p>` containing `<strong>`, `<em>`,
7//! `<code>`, and `<br>` would behave in HTML.
8//!
9//! Inspect `out/inline_runs.tree.txt` to see the Inlines container with
10//! its child Text/HardBreak runs, and `out/inline_runs.draw_ops.txt`
11//! to see the single `Attr ... runs=N` line that draw_ops emits — one
12//! attributed text op per paragraph, with all the styling baked in.
13//!
14//! Run: `cargo run -p aetna-core --example inline_runs`
