Peek class Null safety

🔲 Peek

Consider Peek to be a description of how the 📚 BASE is exposed behind the 📚 MATERIAL.

🔲 Peek.peek is applied as insets to 📚 SurfaceLayer.MATERIAL.


According to 🔲 Peek.alignment and Peek.ratio, a side(s) is given special treatment.

Defaults Alignment.center such that no side(s) receive(s) special treatment regardless of 🔲 Peek.peek.
