/* The Documentation view in the orange design of September 26, 2026 (the owner's archive, site/Docs.dc.html), inside the site's
   one header and footer. Under the header sits the documentation's own bar: the sections of the documentation as tabs in their
   own scroll region, and a search control that is a field on a wide screen and an icon on a phone. The index shows the pages as a
   compact grid of cards. A page has the list of pages on its left, the page itself in a reading column of 760 pixels, and its
   contents list on its right, so the title, the one-line summary and the contents list are in the first screen of a wide window.
   Below 1240 pixels the contents list folds above the page; below 1000 pixels the list of pages moves under the page. No part of
   the view is wider than a 320 pixel screen: a table or an example scrolls inside its own frame.

   Every colour, typeface, radius and shadow is a token from the top of service.css. A token the orange foundation adds has its
   design value written beside it, so this file reads the same before and after that block lands. */
