Mode switching, back where you can reach it. The Chat / Thought / Ghost mode button returned to the consolidated main header. Clicking it opens a picker with a short description of each mode, and it closes on an outside click or Escape. It reuses the existing mode machinery, and it's styled to sit cleanly alongside the other header controls — Translate, Neurons, Refresh — instead of looking bolted on.
Room branding, dialed back. Custom per-room logos were removed from the chat header and the sidebar room list, which now show the default GroupGPT mark and a lock icon respectively. The room Appearance tab in Room Settings — where logos, bio, website, and colors were configured — was retired along with the room profile card that displayed them. The contrast on the remaining Room Settings controls was raised at the same time, so the labels, helper text, and buttons that were nearly invisible on the dark modal are now clearly legible.
A note on scope: this is room branding. Your personal profile — avatar, display name, bio, and link — is a separate thing and was untouched.
Why it matters
Putting mode switching back in the header restores a core interaction that quietly went missing, and matching its style keeps the header coherent. Stepping back room branding simplifies the product surface and the settings screen — and raising the modal contrast fixes a real legibility problem at the same time.
