 * its only accepted values were the generic defaults, so no property name was
 * writable. The vocabulary is derived from the Look property table rather than
 * listed by hand (D57 rule 134): every animatable Look property, spelled the
 * way CSS spells it, plus the two aggregate keywords. A property that does not
 * participate in interpolation is excluded for the same reason `keyframes:`
 * rejects it.
 *
 * The set is published because the longhand is not its only reader: charter
 * section 3549 says the `transition(property, ...)` builder takes the same
 * vocabulary, so the analyzer's literal-argument check and the builder's own
 * runtime guard read this table rather than restating it.
