yoga-layout 3.2.1: Yoga 3 defaults to BoxSizing.BorderBox where fixed dimensions include padding and border, configures flexShrink 0 and Column direction unless useWebDefaults is enabled, restricts measure functions to leaf nodes with dirty-mark caching, collapses Display.None geometry, and recalculates cross-axis dimensions from aspectRatio

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- Yoga 3 defaults node box-sizing to BoxSizing.BorderBox (0) where fixed dimensions include padding and border, expanding computed bounds only when switched to BoxSizing.ContentBox (1)
- Config defaults useWebDefaults to false with flexShrink 0 preventing overflow compression, while useWebDefaults(true) enables Row direction and flexShrink 1
- Measure functions are leaf-only, cached across layout evaluations until markDirty is invoked, and abort if children are inserted
- Display.None collapses computed layout rectangle to zero dimensions and removes the node from sibling flow calculation
- AspectRatio dynamically recalculates the cross-axis dimension from the main-axis dimension during layout
