1//! The [`Html`] view on its own: a whole HTML fragment as the screen.
2//!
3//! ```bash
4//! cargo run -p tuika-html --example html_view # a real terminal (q quits)
5//! ```
6//!
7//! The companion example, `html_markdown`, shows the *boundary* — HTML blocks
8//! inside a markdown document. This one shows the **component**: no markdown
9//! anywhere, `Html` placed in a layout exactly like `Markdown` would be, fitting
10//! its content to whatever width the pane gives it.
