/* ── Blog flagship layer ───────────────────────────────────────────────
   Brings blog posts up to the homepage standard: real colour separation,
   left-aligned reading measure, data graphics, real app screens.

   Loads AFTER design.css. Everything is namespaced bf- so it cannot
   collide with design.css or home-flagship.css, which share .tile,
   .eyebrow, .fact, .sec and .price between them.

   --display is Plus Jakarta Sans from design.css; never override it (Aaron, 2026-09-09). */
