   SMOOTH-P3b. "I know what I want".

   Six kind tiles in a two-column grid, then rows of chips. Every choice
   is a native radio or checkbox inside its label, so the whole chip is
   the target (48px tall) and state is the browser's own. The checked
   chip is bold with a 2px border as well as coloured, so it never rests
   on colour alone (1.4.1). Focus shows on the chip (focus-within).
