/* Motion (her «давай пробуем», 2026-11-04; animate + Emil's rules): occasional → a standard popover animation whose job is
   spatial — the stack unfolds out of the button's corner and folds back into it (transform-origin = the button, set by
   contact.js). Open: the stack 0.96 → 1 + fade, 200 ms strong ease-out, the cards follow 40 ms apart from 6 px off.
   Close: faster (150 ms), all at once, no stagger. Transitions only, so open/close mid-way just turns around. */
