/* ============================================================================
   BLOB BATTLE - style.css
   The page around the game: it fills the whole window, removes every trace of
   browser furniture, and draws the on-screen joystick and SPLIT button for
   phones and tablets.

   Every colour and shape here is written by hand - no web fonts, no icon
   packs, no images. Nothing in this file asks the network for anything.
