/*
 * Today screen visual theme (ticket 9v690s).
 *
 * Ported from the approved prototype (slnpjy):
 *   prototypes/today-screen-and-per-set-logging.html
 *
 * Custom properties, class names, and the tick-flash keyframe are carried
 * forward as closely as practical; layout is adapted from the prototype's
 * "phone mockup" frame to a real full-viewport mobile page.
