Research direction

Investigate the pixel alignment logic in QMUI iOS, specifically the use of ceil for rounding line heights. Compare with system rendering on 3x screens (e.g., iPhone 14 Pro Max) to understand why lines with the same 0.5 point value result in different pixel heights (0.33 and 0.67). Check how UIView's contentScaleFactor and anti aliasing interact with the rounding function.
