/* Settings -> Rooms.
 *
 * Layout, hierarchy and interaction follow the Rooms redesign handoff;
 * the colours do not. The handoff specifies its own green and grey ramp,
 * which would make this the one page in Settings that looks like a
 * different product. Every value below maps onto the admin tokens in
 * base.css instead, so Rooms inherits themes like every other page.
 *
 * The load-bearing idea: a room is configured once and then checked on,
 * so the default state is a scannable list of facts and editing is
 * something you enter deliberately.
