   Login success transition ("the climb ritual"), three stages:
   1. is-success  -- Ascend button swaps to a check, dark green, one pulse
   2. is-leaving  -- form rises out (exit), glow bar sweeps upward once
   3. is-ascending on .creed -- the five creed lines light up bottom-to-top
   All motion is transform/opacity/filter only. Total ~700ms, then redirect.
