//! impeccable-detect: `impeccable detect` orchestration and the non-DOM
//! engines, ported from `cli/bin/cli.js`, `cli/engine/cli/main.mjs`,
//! `cli/engine/node/file-system.mjs`, `cli/lib/impeccable-config.mjs`,
//! `cli/engine/engines/regex/detect-text.mjs`, `cli/engine/design-system.mjs`,
//! `cli/engine/profile/profiler.mjs`, and `cli/bin/commands/ignores.mjs`.
//!
//! Engine seams: [`engines::HtmlEngine`] (static HTML, crates/html) and
//! [`engines::UrlEngine`] (browser, crates/browser). This crate never depends
//! on those crates; the `cli` binary wires them in through
//! [`engines::Engines`]. crates/html depends on this crate for the design
//! system types and helpers ([`design_system`]).
