/* ==========================================================================
   HYPER LOGISTICS — design system

   Structure follows the reference the client approved: dark page, one accent,
   photography-led sections, a card for every idea. Everything is designed at
   375px first and only widened at breakpoints — the client judges this on a
   phone, so the phone layout is the real one.

   Accent is electric blue. Amber is reserved for star ratings alone, so the
   blue never has to compete with a second bright colour for attention.
