Light and dark mode

The CRM ships in a dark theme by default. To switch, tap the sun/moon toggle in the top bar: it flips the whole app between light and dark in one tap. Your choice is saved on the device you're using, so each team member can pick what suits them without changing it for anyone else. The public marketing site stays light; only the signed-in CRM follows your toggle. The product tour points the toggle out on your first visit, and you can switch back any time.
