/* ---------------------------------------------------------------- carousel

   No JavaScript anywhere on this site, so the current slide is held by a
   hidden radio group and the dots are its labels. Everything below is sibling
   combinators, which have worked since CSS2.

   Two earlier attempts are worth recording, because both looked right:

   1. A scroll-snap track with the dots as plain anchors, on the theory that
      the browser scrolls the nearest scrollable ancestor to reach a fragment.
      Measured: clicking a dot left scrollLeft at 0, every time.
   2. `:target` on the slide plus `.carousel:has(#slide-0N:target)` to move the
      track. That works on a page *loaded* at #slide-04 -- measured, the track
      really is translated -- and does nothing when the hash changes, because
      Chrome does not re-evaluate `:has()` when `:target` moves. A control that
      works only if you arrive by deep link is not a control.

   Radios also come with keyboard support for free: tab to the group, arrow
   between slides. */
