//! UA inline chrome — the paint-time text substitutions the built-in
//! elements supply, gathered into one table for the paint pass.
//!
//! Each entry is a built-in's `inline_chrome` adapter: given an element
//! and the single-row width available to it, return the
//! [`ChromeText`] to paint in place of the element's own text, or
//! `None` when the element is not one of that built-in's. The entries
//! are disjoint by tag (`<progress>` / `<meter>`, `<select>`,
//! `<input type="password">`), so table order never changes a result.
//!
//! The paint pass reaches this table through exactly one call
//! (`render::paint_pass::inline_paint::chrome`), and that file says
//! why the table is compiled in rather than registered per `Dom`: a
//! bare `Dom<TuiExt>` painted without `App::build` must still show its
//! chrome.
