 * Section: upcoming sessions (the "jl-upcoming" group).
 *
 * A heading, intro and button on the left; on the right the next sessions
 * from the schedule, one row each. The rows come from the [jlaude_upcoming]
 * shortcode (inc/upcoming.php). The split layout is meant to hold up whether
 * there are six sessions, one, or none: with none, the "jl-upcoming__empty"
 * note takes the place of the list.
 *
 * Colours, fonts and edge spacing come from the theme. The reveal only starts
 * once the script is running (html.jl-js), and each row waits until it is on
 * screen.
