/* ==========================================================================
   Tools nav — cross-links between the 4 tool pages.
   Sits directly under the site header. Uses main.css's palette tokens only.
   Mobile-first: horizontally-scrollable pill row at narrow widths, wraps on
   wider ones. Each pill is a >=44px tap target (--touch-min).
