/* The article list stops working as a table well before phone width: measured against the

   880px both sit comfortably. So below 820 — which also covers tablets in portrait — each
   row becomes a card. The markup keeps its table roles (see index.html), so the visually
   hidden header still names the fields. Order is deliberately not the column order: the
