+//! ## SPIR-V frontend
+//!
+//! This namespace contains the SPIR-V parser and translator used to import shader
+//! modules into the compiler IR.
+//!
+//! `Parser` validates the SPIR-V header and iterates over binary instructions.
+//! `spec` exposes a minimalistic SPIR-V header translation.
+//!
+//! The main entry point is `translator.translate`, which finds the requested entry
+//! point, maps its execution model to an IR shader stage, lowers supported types,
+//! constants, interfaces, instructions, and structured control flow, then validates
+//! the generated IR module.
