Dark mode, a roomier layout & more

A big update to Class Chat — here's what's new:

• Dark mode — switch it on in Settings → Appearance (Light, Dark, or System).

• Collapsible sidebar — collapse the left sidebar down to icons for a wider chat view.

• Members & invites in chat — see who's in a class and invite classmates right from the chat header.

• Faster sign-in — sign in with a 6-digit code sent straight to your school email.

• Cleaner messages — a sender's messages now group together and bubbles fit their text.

• Delete your account — you can permanently remove your account and data from Settings.
