A right-angle turn can produce a tiny negative dot product. Compare it
relative to the axis lengths before treating the turn as a reflection.

Red regression reproduced at small, normal and large sizes. Focused
geometry, reset, swap and runner suites pass 121 tests / 540 assertions.

Benchmark vs Phase 1e: main 10/100/1000 0.51/0.64/0.65; levels 0.50;
chain 0.57; library 0.53; many shapes 0.47; switch 0.59. No flags.
