fix: button text unreadable on hover (a:hover overrode accent button text color)
The global a:hover{color:var(--accent)} flipped the text color of every accent
button that is an <a> to the accent color → text = button background = unreadable
(noticeable on sites with a vivid accent, e.g. sound-fabrics #ef2840). Override
added: button anchors keep their own text color on hover (.btn/.epk-btn = ink;
primary/danger/success/feature = white). style.css cache-buster v9->v10.
