/* ═══════════════════════════════════════════════════════════════════════════
   tools-hub.css — the ONE design for the tool hubs: /free-tools and /calculators.
   Both pages render their catalogue from $TOOLS_CATALOG (partials/_tools_data.php)
   and link this file; neither carries its own copy of these rules any more.

   Everything is scoped under .au (the au- light palette from _au_base.php).
   Naming: .ft-* = hub furniture shared by both pages, .ch-* = search / status /
   empty state (born on /calculators), section "free-tools additions" = the
   chips, type filter, most-used strip and ranked results used by /free-tools.

   Trap (theme-light.css): any class containing "-card" (not -card- / -cards /
   -card__) is repainted white with a border. .ft-card IS a white card, so that
   is fine — never give a DARK surface a *-card class here.
