/* volunteering.css
 * Chapter-based volunteering page, ported from the DesignCombo prototype
 * ("Volunteering Page Redesign") into native HTML/CSS/JS. Full-viewport
 * scroll chapters with a fixed progress bar + dot nav (desktop), a read-more
 * expand per chapter, and an "All memberships" closing grid.
 *
 * All behaviour is progressive enhancement: without JS every chapter and its
 * expanded copy still render in normal document flow (see .no-js fallback in
 * volunteering.js). Prefixed .vp-* to stay isolated from the shared styles.
 */

/* Gentle full-page snap between chapters (proximity, not mandatory, so the
 * shared header and footer stay easy to reach). Only loaded on this page. */
