Swell
A small, steady icon vocabulary for reading the coast: natural forces, station hardware, and the controls that bring their measurements together.
Eighteen single-purpose symbols, drawn on the same quiet, open line.
One outline form stays clear from a compact control to a display-size mark.
A station overview uses the same symbols for readings, actions, and alerts.
Reference a symbol with <use>. Decorative marks stay out of the accessibility tree; meaningful ones get a name.
