/* Match Material's content grid to this page's own content width.
   .md-grid governs the HEADER and TABS bars as well as the article, so if it
   and .viz-root .wrap below disagree, the header runs to a different width
   than the content under it and reads as left-aligned against a centred page.

   This was previously `92.5rem`, written expecting 16px rem = 1480px. It is
   not: mkdocs-material scales the root font size (125% -> 20px, and 137.5% ->
   22px above 100em), so 92.5rem resolved to 2035px — wider than almost any
   viewport, which let the header bar go full-bleed while the content stayed
   centred at 1400px. Stated in px so the root-font scale cannot drift it
   again, and matched to .viz-root .wrap. (Material's own default grid is
   64rem = 1408px at that scale, so this also keeps the page in line with the
   rest of the site.) */
