/* =================================================================
   Article header: the text, with an optional video tutorial beside it
   -----------------------------------------------------------------
   Every guide carries an empty video slot. kb.js reveals it only once
   it finds a usable YouTube id in data-kb-video, so a guide with no
   recording keeps the plain full-width header it always had -- and a
   half-filled attribute cannot leave an empty black box on the page.
   The parent gets .has-video from the same code, rather than :has(),
   because the slot already depends on that script having run.

   Nothing is requested from YouTube until the reader asks for it: the
   poster is a thumbnail, and the iframe is built on the click. That
   keeps a guide page free of third-party frames for anyone who only
   came to read, and it is the reason the slot is a <button>.
