/* Prodsystem — product-led landing page
   [PRODC-203 | S14 | v0.1.0] Landing page: product-led light redesign with real application screens

   The product is the hero: every large visual on this page is a real screen of the
   application, captured from a demo instance (landing/tools/). The palette is the
   brand's own: the violet of the Prodsystem logo (wordmark #2e0c64, mark light →
   deep violet) as the primary, the application's sky #0e91e6 as the highlight,
   slate surfaces and Inter as in the app — so logo, page and screenshots read as
   one brand. Light throughout; one deliberate dark section (self-hosting). */
