axe-core flagged 18 'button-name' criticals on the room view: the space
tabs, Home/Direct/Inbox/Search/Saved/Explore/Add Space/User Settings/
Unverified sidebar buttons, and each message's avatar button had no text
for screen readers. Labels mirror the existing tooltips; message avatars
read '<name>, open profile'. Room view now has zero button-name findings.
