Reduced motion is no longer silent (console notice, essential, DSSL.motion). animate: gains delay,
jitter, iterations, essential; motions are shared across files; keyframes accept 0%; every motion is
a real @keyframes; animate: works on pseudo-elements; DSSL.play(). Layered gradient sentences,
text-stroke, bare custom shadow/radius tokens, paint-order and conic-gradient(from ...). Author
inline styles win; static subtrees; aura clip/scale/z; @signal in/not in/!=; DSSL.lint(root);
dssl check/build take an index.html. Docs checked against the real API by test-v0140.
