Greptile Summary

This PR adds support for the CSS min() function, mirroring the existing max() handler. It also expands the CSS functions test suite with new tests for min(), max(), calc(), and nested combinations, and fixes the pre-existing fontScale/pixelRatio tests to properly mock PixelRatio values instead of relying on environment defaults.

• New min() handler added to processFunction using Math.min(...), placed immediately before the identical max() pattern.
• Test suite expanded with min, max, calc, and combinations test cases; fontScale and pixelRatio tests now mock PixelRatio and clean up with mockRestore().

Confidence Score: 5/5

Safe to merge — the change is a minimal, well-tested addition that follows an established pattern already used for max().

The min() handler is four lines that exactly mirror the max() implementation, a pattern that has been in production and is now covered by the expanded test suite. The test file improvements (proper mocking with mockRestore cleanup, nested combination tests) increase confidence in the whole functions pipeline rather than just the new case. No existing behaviour is changed.

No files require special attention.

Important Files Changed

Filename	Overview
packages/uniwind/src/bundler/css-processor/functions.ts	Adds a min() handler in processFunction — 4 lines, mirrors the existing max() block exactly. No concerns.
packages/uniwind/tests/native/styles-parsing/css-functions.test.tsx	Adds min, max, calc, and combinations tests; improves fontScale/pixelRatio tests with proper mocking and cleanup. Test math expectations are all correct.
