v5.3.4

A static page is no longer painted twice.

Fixes

• A pre-rendered page is taken over in place. When a static build's
  script arrived it drew the whole page again and replaced the one already on
  screen. The reader saw nothing change, but the browser painted the page a
  second time — and once a web font had arrived, the second paint of the
  largest paragraph or image was larger than the first, so it became the
  page's Largest Contentful Paint. On a phone a page that was readable in
  under a second scored an LCP of 3.6 s. The script now draws beside the
  painted page and takes it over: an element nothing holds stays exactly as
  painted, its attributes brought up to date; one a handler, an effect, a
  ref, a widget or a list holds is put where the painted one stood. The
  first paint stays the largest, and the reader keeps their scroll, focus and
  selection. A page that cannot be matched is drawn again whole, as before.
• Under wf serve, a takeover is checked. The runtime compares the page
  it took over with the one it drew, and says so in the console when they
  differ.
