Accessibility
Tutor should be usable with a keyboard, a readable type scale, and labels on icon-only buttons. Forms expose names for inputs, and dialogs can be closed with Escape where that pattern is implemented.
If a screen, contrast choice, or control blocks you from booking a lesson or opening a course, send a note from Help & Support with the page URL and what you tried. We treat that as a product defect, not a feature request.
