• Canonicalization: don't suggest invalid calc(…) expressions (e.g. px-[calc(1rem+0px)] → px-[calc(1rem+0)]) (#​20127)
• Canonicalization: avoid suggesting large spacing-scale values for arbitrary lengths (e.g. left-[99999px] → left-[99999px], not left-24999.75) (#​20130)

• Canonicalization: don't fold calc(…) divisions when the result would require high precision (e.g. w-[calc(100%/3.5)] → w-[calc(100%/3.5)], not w-[28.571428571428573%]) (#​20221)
• Serve ESM type declarations to ESM importers of @tailwindcss/postcss (#​20228)
