//! Shared fluent-builder methods for [`Build`](crate::build::Build) and
//! [`Dev`](crate::dev::Dev).
//!
//! Both builders accumulate the same source inputs — a list of roots and a
//! [`Processors`](crate::build::Processors) set — so the methods that set them are
//! written once here and stamped onto each builder by [`source_builder_methods!`], the
//! same `macro_rules!` + `pub(crate) use` approach `cli_config`'s `feature_args!` uses.
//! Each builder then adds its own mode-specific methods (`Build` its output/vendor
//! options and `run`, `Dev` its `serve`/`router` terminals), all in the
//! `self`-consuming, `Self`-returning chain style of [`Frontend`](crate::Frontend).

/// `roots: Vec<PathBuf>` and `processors: crate::build::Processors` fields.
