/* /what-we-build/ranking: the first capability page. Layers on top of
   base.css.

   Section order matches src/views/what-we-build-ranking.ejs and the
   capability-page structure in SITE-ARCHITECTURE.md section 5.

   Most of this page is already shared. The three cards under "What this
   settles" and the two under "Two that work with it" are base.css's
   .hub-grid and .hub-card, and the teal marks above two headlines are
   the shared .accent-rule. What is left here is the hero, the two-column
   split inside the dark band, the ranked table, and the closing block.

   The ranked table is the one genuinely new component. It is built as a
   real table because the rows are data and a screen reader should be
   able to move through them by column. */

/* Below 820px the table cannot hold a readable reason line and two

   The first build let it scroll sideways inside .rk-table-wrap. That
   technically worked and was the wrong answer: on a phone the reader saw
   company names and clipped reasons, and both scores sat off the right
   edge behind a gesture nobody was told about. The scores are the entire
   argument of this page, so a layout that hides them by default fails
   here more badly than it would anywhere else on the site.

   So below this width each row stops being a table row and becomes a
   stacked block: rank and company, then the reason, then the two scores
   one above the other. Stacked rather than side by side on purpose, so
   the two bars share a left edge and the same scale, which is what makes
   a 100 sitting above a 68 legible at a glance. */
