- chat: left-aligned discord-style messages with grouped senders, hover
actions, an auto-growing composer and file cards
- send: render messages and files locally first and replace the
placeholder when the worker publishes the real item; failures keep the
text with a retry action
- navigation: space rail plus a flatter channel list with the space name
header and collapsible groups
- members: right pane tabs (files / members) grouped by online, offline
and pending users, with a prominent invite action and a top bar shortcut
- notifications: toast host for invite results; invitees get a toast with
an accept action, and the invitation payload now carries the space name
and inviter inside the encrypted grant
- users over devices: drop device names, the device list and device
rename/release; senders show the account (guests show as guest) and the
share panel only keeps links
- follow contract 7.0.0 (max_members, members_used, members_full, /join)
- docs: ui-design and frontend updated for the new layout and concepts
