/* Premium buttons v2 — flat colours, no glow, no gradients. Active only under <html class="kvb">
   (now: the owner's test page; to release, add the class, this stylesheet and js/buttons-premium.js to the public page).
   Hover: a solid circle spreads from the point where the cursor came in (and shrinks back to where it left);
   the button lifts by 2 px. Press: the button sinks a little and a soft wave runs from the touch point.
   Position of the circle comes from js/buttons-premium.js (--kx/--ky/--kd); without the script it grows from the centre.
   `translate`/`scale` are used instead of `transform`, so buttons that are centred with transform keep their place. */
