clean-room control page — zero shared code with the real app

  
Scroll test: no framework, no build step, no app code

  

    This page exists purely to test whether a real iOS Chrome / Safari scroll bug
    (scrollY getting dragged back toward the top for a few hundred ms, then settling)
    reproduces here too. Nothing on this page shares any code, CSS, or JS with the
    real driftless/tiny sliver app — it's a single static HTML file with inline
    CSS, no framework, no bundler, no hydration, no lazy-mounted components, no
    ResizeObserver/IntersectionObserver-driven layout changes of its own (other than
    the optional diagnostic overlay below, which only observes, never causes,
    scrolling). If the bug still happens here, it isn't caused by anything in our
    app's code — it's the browser, the OS, or something environmental. If it
    doesn't happen here, that points squarely back at the real app.
  

  
Scroll down through the sections below on your phone the same way you normally
    would on the real landing page, and see if the same fighting-back sensation
    happens.

Section 6 — end

    
That's the bottom of the page. If you made it here fighting the scroll the
      whole way, the bug reproduces on a totally clean page with none of our app's
      code — meaning it isn't us. If it scrolled smoothly, the opposite.
