   workspace bg: #E7E9EE flat office-chat grey (the rest of the app, out of focus)
   chat header: #232B3D slate, online dot #35C46A
   bubble: #FFFFFF panel on #E7E9EE, border #D7DBE3
   ink: #1B2230 (sender/caption), #6B7280 (muted/seen line)
   link-preview card: #F4F5F7 fill, #D7DBE3 border, tag colour #3457D5 (office-blue accent,
     solid, not a gradient)
   photo/attachment palette comes from the art itself (mustard hallway, brown doors, pig pink) -
     chat chrome stays cool/neutral on purpose so the candid photo reads as the one warm thing
     dropped into a grey app, the way an office photo actually looks pasted into chat
   type: Karla (UI text, self-hosted woff2) + Overpass Mono (timestamps/CA/link meta,
     self-hosted woff2), no CDN
   corner radius: 6px on the bubble/photo/link-card (real chat-attachment radius, not a
     generic soft-UI 16px+ card), 0 elsewhere
   motion: one three-dot "typing" beat before the message appears, once, on load. prefers-
     reduced-motion skips straight to the message.
