   content-box radius doesn't shrink to match the padding exactly), which is
   the "espacios en blanco" — gaps of page background peeking through at the
   rounded corners. Instead: ::before is a full, blurred, rotating gradient
   disc sitting behind the card; ::after is the card's own flat surface,
   sized exactly to the card (inset:0, radius:inherit) and stacked on top,
   masking ::before back down to nothing but a clean ring with no seams,
   because there's no boolean mask math — just two solid shapes overlapping.
   Breathing lives entirely on ::before, safely, since even at its dimmest
   there's still a full gradient disc underneath — never a gap, just fainter. */
