   and a soft indigo glow instead of a neutral drop shadow.
   :not(.bg-gray-900):not(.bg-indigo-500) lets this be applied as a
   permanent class on JS-toggled filter pills — it steps aside automatically

/* No added box-shadow here on purpose: category/brand pills already sit in
   front of a floating .nav-hover-pill (see below), which supplies its own
   glow — stacking a second shadow from the chip itself doubled up into a
   fuzzy, misaligned smear.
   This used to be a plain `hover:bg-white/70` Tailwind utility, but a bare
   :hover class always outranks a single class like .bg-indigo-500 on
   specificity — so clicking a pill while the mouse stayed over it (the
   normal case) let the hover-white win over the active indigo/black fill,
   leaving white text on a white pill. Keeping the guard here fixes that:
   it steps aside whenever the pill is actually selected. */
