   LUPO premium layer, shared atmosphere + motion.
   Loaded on the lighter subpages (pricing, demo, sales-ops, faq)
   to match the cinematic treatment on / and /how-it-works.
   Pure CSS depth: no images. Reveal classes are applied by
   premium.js, which is safe-by-construction (no JS => nothing
   hidden; reduced-motion => nothing hidden).
