Found while testing crates/geom/src/lib.rs (no existing issue): the builders replaced NaN and infinities with 0 but took any finite size, and kurbo subdivides an arc in proportion to the sixth root of its radius, so ellipse(1e36, ...) built about a million cubics and 1e60 never returned (sizes arrive from files and commands). The sanitizer now also clamps magnitudes to MAX_COORD (1e9, the bound measure::finite_path already uses). Polyline::nearest returns None for a non-finite point instead of Some((NaN, NaN)). Tests cover 1e36, 1e300 and f64::MAX for every builder. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
