   Concept: the studio does not sell a body, it sells a slower tempo. Every other
   yoga site in the category is beige and sage with a backlit stretch photograph;
   this one is the colour of 6.30pm — the hour of the class people actually come
   to after work. Time is the unit of measurement everywhere: the breath bar runs
   on the 4-in / 6-out count the teachers actually use, and a class block is as
   tall as the class is long.

   Everything transitions at 400ms rather than the usual 200ms. Nothing on the
   page is allowed to hurry.

   Signature: the breath bar (.breath). Once, in the hero, and nowhere else.
