Put together a UI kit (typography, buttons, logo lockups, color system) alongside the page — treating even a single screen as part of a reusable system, the way it would be handled in a real product.
Kept the "404" large but faded in the background so it doesn't compete with the navigation options — the goal was recovery, not decoration.
Added quick links to the platform's core service categories (Trading, Logistics, Procurement, Support, Supply Chain), so a lost user can self-navigate without going back to the homepage first.
Built as a system, not a one-off
