/*
 * status.rostack.app
 *
 * Roblox's status page structure (a verdict banner, the services grouped and
 * listed with their state, then the history) in Rostack's own palette, with
 * ninety days of availability under every service.
 *
 * Plain CSS and no framework: this page exists for the moment everything else
 * is broken, so it depends on as little as possible.
