The article shows how to eliminate per-component spinners by moving data fetching into route loaders and preloading that data on hover or intersection. Route transitions then delay navigation until all required data is ready, making pages appear fully rendered instantly. A single global loading indicator handles only cases where data truly takes too long or on full page refresh.

• Route loaders that preload data on hover/intersection let pages appear fully rendered instantly instead of flashing spinners after render
• Empty UI during development becomes a useful signal that you forgot to preload something, rather than a gap to paper over with a skeleton
• A single global indicator (like GitHub's top progress bar), delayed a few hundred milliseconds, replaces scattered per-component loading states for the rare genuinely slow fetch
