/* ==========================================================================
   BYB Global — Resources hub + detail (Phase 12)
   Built on the homepage's own patterns (home-v2.css), same as Service Detail:
   centred world-map hero with framed eyebrow + scroll cue, tag → serif
   heading → gold-rule section heads, hairline gold grids with the growing
   gold indicator bar, 96px section rhythm, full-bleed dark gold-gradient
   final CTA. Scoped to .res-page; shared by page-resources.php (hub) and
   page-resource.php (detail). Sharp corners everywhere except buttons.
