/**
 * djtutor.com :: browse-sections module (mod_djtutor_sections)
 *
 * Entry points to everything outside the curriculum. Built from the --djt-* design tokens only,
 * so the brand and the light/dark scheme come for free.
 *
 * Layout: a tinted band that bleeds to the viewport edges (no extra markup: a huge box-shadow
 * clipped to the element's own height), with three cards in the first row and two wider ones in
 * the second, so none of the five is squeezed. Each card reads as count | title + text, with the
 * section's accent colour on the leading edge.
