/* Alumni Nations — Pricing / Self-Service Signup Page
   =====================================================
   Shares the product's brand tokens (navy/gold, see ../style.css) but is
   its own stylesheet rather than an extension of it -- ../style.css is
   tuned for the narrow, single-"screen"-at-a-time upload tool; this is a
   wider, scrollable marketing page with sections a tool UI never needs
   (hero, pricing grid, FAQ). Sharing one file would mean either cramming
   marketing-only classes into the tool's stylesheet or fighting its
   already-narrow .wrap/.screen layout assumptions. */
