   Deliberately a SEPARATE media block placed AFTER the #nav a.navlink / #nav
   .navbadge base rules directly above -- not merged into the earlier
   `@media (max-width: 1023px)` block near the top of this file, which sits
   BEFORE those base rules in source order. Same selector => same specificity,
   so a media-query override only wins the cascade if it comes LATER in source
   than the rule it's meant to override (this is exactly the #nav .navfoot bug
   fixed earlier in this file, avoided here by placement). flex: 1 1 0 +
   min-width: 0 is the key invariant: it forces the 5 tabs to divide the row
   equally and shrink below their content size instead of overflowing it,
