//! Back-compat shim. The full PPC disassembler now lives in
//! [`xenia_cpu::disasm`] (single source of truth, sitting on top of the
//! canonical decoder). This module preserves the legacy `Decoded { base, ext }`
//! surface so existing call sites keep compiling while the analysis crate
//! migrates to `DisasmText` directly.
