/* --- phone: put the two navs back INSIDE the column ------------------------------
   Below 860px the grid collapsed to one column and both navs were set to display:none,
   which left a 77-page documentation site with no in-section route on a phone — the
   hamburger only carries 5 hubs and 5 marketing pages.

   This block must sit AFTER the .doc-side / .doc-toc base rules above: a media query adds
   no specificity, so an equal-specificity rule later in the file would otherwise win.

   Two things that are not obvious:
   - `order` needs a flex context, and 18 of the 38 pages that carry a TOC are a plain
     .doc-shell (display:block), so the flex reset has to cover both shells.
   - .doc-shell.has-side sets align-items:start, which in a COLUMN flex container is the
     CROSS axis — left alone it shrink-wraps .doc-body to max-content and blows the page
     open. It has to be reset to stretch.
   Page contents becomes a scrollable chip row above the article (~50px) rather than a
   vertical list, which would otherwise push the <h1> down past 400px. */
