recipes/room/backend/acts/app/Main.jsx

One file of recipes/room, at commit 9a5bb24.

// app/Main: the act the room shows. Written as an agent or a user would write it, against the
// same `client` a page module gets: `share` for the board, `ask` for the granted call. Two
// screens on a stage of its own, so the room's tail is a real URL on the page.
//
// This file is not part of the recipe's program: `app/Rooms` reads it, turns the JSX into `h`
// calls, and puts the result in the module document the room loads it from.
