/*
 * Admissions Listing section.
 *
 * A two column funnel module. The page jump navigation sits in a sticky card
 * on the left, reusing the shared table of contents markup with the approved
 * card styling from the admissions funnel design. Titled subsections stack on
 * the right: a numbered checklist accordion whose open step turns cream and
 * shows check marked tasks, and a dated timeline with ring markers on a thin
 * rule. Below the large breakpoint the card stacks above the content and stops
 * sticking. Colors are component custom props with light-surface defaults; the
 * purple-surface overrides live in the central page-sections stylesheet under
 * the theme-dark wrapper.
