Subject: [PATCH] design: the Turing page gets the site's menu; the menu pins
 again

/turing/ swaps its two-link header for the shared six-section header.
The shared header had stopped pinning on wide screens on every page:
overflow-x hidden on html and body made the page its own scroll box,
which breaks position sticky. overflow-x clip keeps the no-sideways-
scroll guard without that side effect. Phones keep the scroll-away
header, as site-nav.css intends.
