first layer
Initial covering applied
The first layer is the initial or foundational level of something with multiple layers—whether physical, conceptual, or procedural.
In painting or construction, it's the base coat that subsequent layers build upon.
In neural networks and machine learning, the first layer processes raw input data.
The first layer of paint needs to dry completely before adding another.
The term implies structure and sequence, suggesting more layers will follow.
