/* T-518: the connect-a-screen guide (prototype v5), light only, in the site's own font. Everything is scoped under .gp
   because the theme styles bare section / ol / button / h2 / p / code. Without JavaScript the <ol> stays a readable list;
   with it (.gp-js) the list becomes the rail. The layout answers to the width of the guide's own column (container query),
   not the window: on the how-to page the guide sits in the 8-column text column. */
