/* Swarmchasing site styles. One sheet for every page; colours are tokens on
   :root with a selected dark set (not an automatic flip). The page CSP allows
   this file only: no inline styles anywhere.

   Breakpoints: three widths, and every width query uses one of them (CSS
   cannot name them, so they are written out; the page scripts that ask
   for a width use the same numbers):
     phone    max-width: 720px   (min-width: 721px above it)  one column,
              cards for tables, the header in two rows, folded figures
     tablet   max-width: 960px   (min-width: 961px above it)  the workbench
              steps through its panes, docs drop the side navigation
     laptop   max-width: 1260px  (min-width: 1261px above it)  the workbench
              puts context under its panes, docs drop the table of contents
   Other queries are about the device, not the width: hover, reduced
   motion, colour scheme, a short screen (max-height) and print. */
