/* =========================================================
   NEDA eCAMPUS — THE CONTACT PAGE FAQ, IN CHAPTERS

   Thirty-three questions is too many to scroll (owner, 2026-09-10), so the
   page's own h3 sections become a rail and one chapter's questions show at
   a time. The card, the numeral, the divider and the chevron plate are the
   front page's FAQ (`.neda-fp-faq__*` in neda-front-page.css) rather than a
   third FAQ style: the two are the same component in different columns.

   `neda-faq.css` still styles `.neda-faq` groups elsewhere and is not
   touched here — this markup never carries that class, so the two cannot
   collide.

   STATES follow the Neda control vocabulary: hover and focus are one cherry
   fill with white ink and no ring; the chosen chapter is text-box 4 with a
   black bold label and a 3px inset bar, so selection is never carried by
   the tint alone.

/*
 * HOVER AND FOCUS ARE ONE APPEARANCE, AND THEY COME LAST ON PURPOSE.
 *
 * Hover beats selected while the pointer is on it. These selectors weigh
 * the same as the `[aria-selected]` ones above, so the only thing deciding
 * it is source order - written before them, the chosen chapter kept its
 * text-box-4 fill under the pointer and the label went black on cherry at
 * 4.22:1. The bar stays: `currentColor` follows the ink to white, so the
 * choice is still visible on the control the pointer is over.
 *
 * A control that fills cherry gets no ring around it.
 *
 * THE INK IS NAMED, NOT INHERITED. A chapter is a link, and the theme
 * colours links cherry with a selector that beats a bare class. Measured
 * live 2026-09-10, before the `a.` was added: a hovered chapter computed
 * `color: rgb(215, 38, 61)` on a `rgb(215, 38, 61)` fill - the label gone
 * entirely - and the chosen one was cherry on text-box 4 at 4.39:1, under
 * the 4.5:1 that 15px text needs. The rest state was black and looked
 * fine, which is why this was worth measuring rather than reading.
