// AUTHORED SHIM (not copied). No-op member extensions to the UnityEngine value/component
// shims, added as the M1 compile loop surfaced specific calls from copied engine/view
// code. Signatures mirror the real UnityEngine API at the call sites (arg counts/types
// taken from the decomp). None executes headless — all return safe defaults.
