/* ============================================================================
   po-journal.css — Journal PrimeO
   A magazine, not a blog roll. Everything is scoped under .pj-* so it cannot
   collide with primeo-site / godmaster / wow layers.

   Design brief
   ------------
   No stock photography. Covers are typographic: a rail-tinted field, the mapped
   solution's product render used as a masked backdrop, and the readership rank
   set as a large numeral. The archive's real traffic (≈760k lifetime reads) is
   treated as the hero asset, because it is the most persuasive thing the Journal
   owns. Every card carries the Nexus it legitimately leads to — that is what
   turns an archive into a storefront.
