   VARIANT 6 — VINYASA
   Motion-led. The storefront opens with a moving practice, not a still image.
   Reference cluster: Alo Yoga's calm + Apple-style product motion.

   Art-direction rule: one orchestrated moment, everything else holds still.
   The Flow is the only place anything moves on its own; the rest of the page
   is as quiet as the other five variants. Colour stays strictly on brand —
   ink stage, off-white commerce, magenta and cyan as the two breath states.
