/* PIEAS Society for Physics — site styles.
   Theme colours are the CSS variables in :root; edit those to recolour the
   whole site. Everything below is grouped by area — base + type, nav, hero,
   the content sections, cards, the gallery / publications / events archives,
   the footer, and the responsive + one-off fixes near the bottom. The dashed
   dividers mark where each part starts. */
