/* Voxden: the signing goal's corner capsule (assets/support/capsule.js), on
   the home and download pages.

   A glass tube in the bottom-left corner, filled with ink-like liquid as the
   goal fills: a highlight along the top, a lit rim, no shadow and no glow.
   Pressed, it grows upward into a card that holds the tube at its foot. It
   sits clear of the back-to-top button on the right, under the nav, and out
   of the way while the phone menu is open. */
