tuika-html 0.1.1

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