/* ==========================================================================
   St. Louis Church of God — Concept 01 "Editorial Gateway"
   Shared stylesheet (supplements Tailwind utility classes)

   Aesthetic direction
   -------------------
   Editorial / magazine layout with Swiss typographic discipline.
   Warm limestone + St. Louis red-brick neutrals, cool Arch-steel accent.
   Grid-breaking hero, hairline rules, numbered section labels, fine grain.
   Motif is civic, not religious: the Gateway Arch catenary + riverfront.
