/*
 * DVLA Dealer Listings — How It Works page CSS
 *
 * Design language matches the landing page (dealer-landing.css):
 *   navy hero, gold accents, Poppins font, light-grey content sections.
 *
 * Layout differs: this page uses a two-column body — sticky TOC sidebar
 * on the right (240px), main content column on the left. On mobile, the
 * TOC collapses into a select-dropdown "Jump to section" at the top of
 * the content.
 *
 * Naming: BEM-ish, prefixed `ddl-howto`.
 *
 * Sections:
 *   1. Page width overrides (Hello Elementor constraint override + title hide)
 *   2. Root + utilities
 *   3. Hero
 *   4. Body layout (2-column)
 *   5. TOC (sticky sidebar)
 *   6. Mobile jump dropdown
 *   7. Content sections
 *   8. Callouts
 *   9. Lists, code, defs, Q&A details
 *  10. CTA + buttons
 *  11. Mobile responsive
