// An `inline for` / `for` range bound is a range ENDPOINT, not a count, so the
// count negative-rejection rule does NOT apply to it: negative endpoints are
// valid and an empty/inverted range simply runs zero iterations.
//
// Regression (F0.4 attempt 11, Agra ruling): the spec wrongly lumped inline-for
// bounds with counts (array dim / Vector lane / value-param), which reject
// negatives. Bounds are exempt — `inline for -2..1` iterates -2,-1,0 and an
// integral-float empty range `0..(-2.0)` runs zero iterations. Comptime and
// runtime loops must agree.
