Most data routes run their load with ssr = false, so SvelteKit holds the previous page on screen while the next one's data resolves — with no feedback. NavProgress, mounted once in the root layout and driven by the $navigating store, shows a thin top bar that trickles while a navigation is pending and fades out on completion. Degrades to a static visible bar under prefers-reduced-motion. New --z-nav-progress token sits above the fixed header but below modals/toasts.
