/* The only static file this site serves.

   Deliberately one file and deliberately plain: no framework, no web font, no background
   image. style-src 'self' in the Content-Security-Policy exists for this file and nothing
   else, and img-src is data: only - so there is no URL in here that could fetch anything.

   The board is read on a phone at the dock and on a desktop in the office, so the table
   scrolls rather than reflowing into cards: a pallet's net weight in a column the owner can
   run his eye down is the whole point of the page. */
