/*
 * Nebula Cruise Agenda - frontend schedule styles
 *
 * BEM naming under .nbca-schedule. Uses CSS custom properties so themes can
 * override colors without touching the plugin CSS.
 *
 * Responsive: at <= 600px viewport the table collapses to a stacked card
 * layout where each row becomes a card and cell labels are surfaced from
 * the data-label attribute.
