// Backtick raw identifier in TYPE position (the universal model, issue 0089):
// `` `name `` is the LITERAL identifier `name` used as a type reference, never
// the builtin/reserved spelling. A reserved type spelling (`i2`, `u8`, …) can
// therefore both DECLARE a type (struct / enum / union / error-set / alias) and
// be REFERENCED as that type via the backtick — while a BARE `i2` in type
// position remains the signed-int type (see `add` below) and a bare reserved-
// name declaration still errors (see examples/1141). The backtick is required
// to declare or reference these names; it is never part of the name's text.
// Regression (issue 0089 — attempt-4 universal raw identifier).
