/*
 * Insights articles block (wpta/insights-list), as in the Insights wireframe:
 *
 * 1. The filters as pills ("All" filled in deep teal when chosen), with the search at the end of the row.
 * 2. The featured article: its photo beside the words on laptops, above them on tablets and phones.
 * 3. The other articles as cards, in three columns on laptops and bigger, two on tablets and one on phones, so
 *    each step of nine fills its rows. On two columns, an odd last card runs across both, its photo beside it.
 * 4. "Load more articles", centred and outlined.
 *
 * Empty photos show as a soft grey block of the same size, so the cards line up until photos are chosen.
