 * One stylesheet for the whole site.
 *
 * Dark first, because a barbershop is lit for the mirror and the phone lives
 * on the counter between cuts — but light is designed too, not inverted, and
 * follows the system unless the person picks. Every control a barber touches
 * between clients is at least 48 px tall and reachable with one thumb: the
 * app's sections are a tab bar at the bottom on a phone.
