   OVER the blue of the current database the moment the pointer crossed the
   label: the link half would go grey while the ⋯ half stayed blue. The child
   selector outranks it (0,3,0 over 0,2,0), so this holds no matter which
   stylesheet the bundler emits first — the nav has lost a rule to source
