/* ==========================================================================
   About Us  —  /page/about-svu/
   Loaded only by templates/pages/about.html, on top of main.css.

   Ported from the earlier build's department/about pages. The header, footer
   and navigation come from base.html; the photo banner and the section
   heading come from page-head.css, which this page loads first and shares
   with Recognition & Approvals. What is left here is unique to About Us:
   the split intro, the tab panel, the affiliations and the award cards.

   Colours come from main.css and nowhere else: --blue and --blue-dark for the
   pills, --red for the active pill and the award spine, --ink and --ink-soft
   for text, --page-alt and --paper for the grounds.

   This file used to declare a royal blue of its own in :root, carried over
   from the build it was ported from. Two things were wrong with that. :root is
   the wrong home for a colour one page uses, since every other component reads
   it first. And the shade was a near-miss for --blue, which the department tab
   panel already uses for the same component - so the two panels looked alike
   without ever being the same colour. They share the tokens now.
