See various styles in Sprint guide. Yes, overlaps widget and component. Make it work, as ONE item. Talk through it as wait indicator is the widget, suggestd /implementation/ for some states is as a modal dialogue. Add in lazy loading as a type... since most of these are standard wait clocks, or maybe the Etsy style moving stripes. The few that are clever (fuzzy to sharp image) are just workarounds, and need to move to show they are working still.
