//! Markup profiles: the host rules a markup grammar is read under.
//!
//! Every difference between an HTML document (in-DOM template) and an SFC
//! template is one associated constant here, so the list lives in one place
//! and each branch folds away under static dispatch. The lexer reads
//! [`Profile::TOLERATE_DECLARATIONS`]; the remaining rules belong to the L1
//! tree builder and are declared now so the profile is complete.

/// Which profile a generic function was instantiated with.
