/* Mobile sticky call to action (shared by every landing).
   Markup, last child of <body>:
     <div class="m-cta" data-mcta>
       <a class="m-cta-button" href="https://testflight.apple.com/join/VDhZpJ8W">Попробовать в TestFlight</a>
       <span class="m-cta-note">Бета для iPhone</span>
     </div>
   Mark the hero button wrapper with data-cta-hero and the final call wrapper with data-cta-final.
   The bar shows on phones (max-width 900px) once the hero button has scrolled away, and hides again while
   the final call is on screen. Colours come from the page: set --mcta-bg, --mcta-ink, --mcta-btn, --mcta-btn-ink
   on :root in the landing's own stylesheet. Without JavaScript the bar never shows. */
