/* ============================================================
   BAR根性 - 神戸三宮・北長狭通
   Wet-asphalt theme. VARIANCE 7 / MOTION 4 / DENSITY 3
   Theme lock: dark, whole page. Accent lock: signal yellow.
   Radius lock: 5px everywhere.

   WHY THIS PALETTE. The shop is open 21:00 to 06:00 every single
   day and gives a free drink when it rains. So the ground is wet
   asphalt at night, and the single accent is the yellow of a
   raincoat or a road sign: the colour you actually see in the rain
   after dark. 根性 means grit, and a signal yellow on grey is a
   working colour rather than a luxury one, which suits a bar whose
   charm is that it stays open and rewards you for turning up wet.

   Deliberately unlike 12-bar-sky, the project's other late-night
   bar: that one is a cold blue-charcoal with a pale silver accent
   for the hour before sunrise. This one is warmer in its greys and
   carries a hot accent.
