in scale there are two types of errors: inline errors can be used for field-specific errors, and toast errors can be used for all other types of errors.

details below can be seen in figma

inline errors

these errors are shown right below the field that is in error.

toast errors

these errors should be used everywhere else in the app, e.g. error with adding a fish. Toast comes in from top of screen and sits on top of all text.
