The on_mount hook of a LiveView with a shared canvas (issho), and the
app's own changes to a canvas.
live_session :default, on_mount: [Hakushi.Live] door, in one LiveView:
on_mount Hakushi.LiveA shared canvas is a session of an Issho room (see Hakushi.Issho): this
hook is Issho's (Issho.Live), which takes the room's events in the
LiveView's process and gives them to its canvases, so the LiveView needs
no handle_info of its own for them. A LiveView that has on_mount Issho.Live already needs no other. A canvas with issho in a LiveView
without the hook raises, saying so.
