/* Powerlifting Plan & Progress — cream and clay design system.
   Layout: an app shell. A sticky sidebar on the left, a reading column on the right made of
   soft cards on a warm cream ground; on phones the sidebar becomes a slide-over drawer.
   A deliberately light-only look (cream is the brief), so every colour is set explicitly. */
