Subject: [PATCH] fix(rpast): serve interactive viewer at space root
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds `GET /` to rpast routes. Without it, /rpast on a space subdomain
404'd because the sub-app had no root handler. Now matches the rNotes
pattern: bare domain → marketing landing, in-space URL → app shell with
<rpast-viewer>.
