/* sail.dfive.us — big, plain, and readable on a dock in the sun.

   Several of the crew are not app people, so the whole design answers one
   question per screen: what is being asked of me? That is the biggest thing
   on the page, and the answer is a button you can hit with a thumb in a
   moving boat — 52px minimum, never a link.

   Navy ink on white, one sea-blue accent, green for "I'm in", a warm red for
   "can't". Colour is never the only signal: every state also says so in
   words. One committed light theme, like Schedule and Split — a sunlit phone
   screen is the main use, and dark mode there is harder to read, not easier. */
