/**
 * Block L10 — Landing-page hero rewrite tests.

 * Covers:
 *   - GET / returns 200 HTML to anonymous users
 *   - Headline string + install snippet + 3 CTA hrefs all present
 *   - "Three reasons" column headings render
 *   - "How is this different" pull-quote string present
 *   - Meta tags (title, description, og:title) injected via Layout
 *   - REGRESSION GUARD: the L4 counters tile section still renders
 *     (stable identifier `class="landing-counters"`)
 *   - REGRESSION GUARD: the L5 "Compare to GitHub" CTA still points
 *     at /vs-github
