ReloadTrigger
Stateless trigger for live-preview reloads.
Each call performs a fire-and-forget POST to the server's reload endpoint; the server then broadcasts the event to every connected Server-Sent Events subscriber. Unlike a persistent session, there is no connection to keep alive: a failed call simply means no clients will reload, and the next attempt is independent.
Parameters
host
server hostname
port
server port to contact
endpoint
reload endpoint path (with leading slash)
