unresolvable-spreadA spread in an sz object the build cannot resolve.
csszyx check lists it.A name in angle brackets is a value the message fills in.
[csszyx] unresolvable-spread: This `sz` object spreads a value the build cannot read, so the object falls back to the runtime.
help: use the array form: `sz={[x, { … }]}` in place of `sz={{ ...x, … }}`.
note: the classes of the spread value were not collected, so they produce no CSS unless another source names them.
