# Spectral Ocean

Choose the representation that owns the requested view. Open-water sea states use
explicit frequency-space ownership. A beach-level breaker view uses a coupled
band-limited wave field, coast representation, swash state, foam history, and
sand response. Do not reduce either target to scrolling normal maps or unrelated
foam noise.

This skill contains exemplary examples and assets beyond descriptive guidance,
they're worth studying, referencing, or even copying. Use them sufficiently
when relevant and do NOT blindly skip them.
