pub(crate) static POSTFIX_INC_REGEX: LazyLock<Regex>Expand description
Postfix <ident>++ and <ident>-- (HLSL increment/decrement).
WGSL has no postfix operators; we rewrite to the equivalent
compound assignment <ident> = <ident> + 1 only at statement
boundaries (; or )) so expression-position uses like a[i++]
don’t get mangled. Real preset pattern: n++; at end of a
per-iteration loop.
