Presentation vs Development mode
miyagi supports two different kinds of views:
Development mode shows additional information like if the mock data is valid, if it complies with the provided schema and so on. When using the development server (using miyagi start), this mode is activated by default.
In the presentation mode, miyagi hides this information as this is often irrelevant when showcasing the component library to non-developers. By default, this mode is activated when creating static builds (using miyagi build).
Both views are always available though and can be toggled via the settings menu in the UI. The selected mode is stored in a cookie and will be restored on subsequent visits.
