 * Лендинг how-it-works.html — стили (extracted from inline <style> iter 4)
 * Chat: web-ce466870, iter 4 of p3-other-html-files-inline-style-blocks-extract
 * Strategy: verbatim extract of inline <style> block content.
 *   - Inline contained themed CSS using CSS variables (var(--primary), etc.)
 *   - landing-responsive.css has LEGACY hardcoded values for some shared classes
 *   - This file loads AFTER landing-responsive.css → overrides (same as inline did)
 *   - Pure refactor: same CSS source, no semantic changes
