/* Cars Driven — the whole stylesheet.
 *
 * ONE global stylesheet in its own file rather than a <style> block, which is worth doing
 * beyond tidiness: ../tomica-tracker-cf hit four bugs that came from a single global sheet
 * (a progress bar given the class `.bar` collapsed the header, which already owned `.bar`;
 * `[hidden]` lost to a later `display` rule and needed `!important`). Rules in one file make
 * "does this class already exist?" a grep instead of a scroll. Both of those traps are
 * pre-empted below.

   There, the photos were product shots on a white backdrop, so the photo panel had to be white.
   Here the photos are whatever I happened to snap of a real car in a real car park: mixed
   lighting, no consistent backdrop, frequently none at all. So the photo panel is a NEUTRAL
   grey that flatters neither and clashes with nothing, and the table — not the photos — is the
