/* "Избранное" toggle on the product page - button, not <a>, needs its own
   reset (border/background don't inherit .cta-btn's <a> defaults).
   Styled in the same language as .buy/.ask (requested 2026-07-17: "в стиле
   других кнопок") instead of the earlier one-off muted/red treatment:
   not-yet-favorited looks like .ask (accent outline), favorited looks like
   .buy (solid accent fill) - same two visual states the other CTAs
   already use, just toggled by click instead of being fixed per button.
   ⚠️ Bug found 2026-07-17 ("кнопка выше в строке, чем остальные") - this
   used to reset `font: inherit`, which (being the font SHORTHAND) wipes
   out font-size/line-height too, not just font-family - a <button> has no
   reason to inherit those from its container instead of getting .cta-btn's
   own 17px/600 like the <a> buttons next to it, and the resulting size
   mismatch is exactly what threw off the vertical alignment. Fixed by
   resetting only font-family (the one thing a <button> actually needs
   fixed - browsers give it a UI font, not the page's font-family) and
   letting font-size/font-weight/line-height fall through from .cta-btn
   normally, same as .buy/.ask do. */
