Summary

• replace spinner-only route loading states with page-shaped skeleton placeholders across the main dashboard, list, detail, conclusion, and webhook screens
• add a shared skeleton primitive plus shimmer theme tokens so placeholders stay visually consistent with the existing theme
• keep the page chrome visible while data loads so transitions feel anchored instead of blank

Why

Several pages were dropping almost all structure and showing a centered spinner during initial fetches, which made navigation feel jumpy and hid the shape of the page while data was still on the way.

Impact

Loading states now preserve the layout and intent of each screen, making route transitions feel steadier and easier to scan.

Validation

• pnpm --dir packages/web test
• pnpm --dir packages/web build

Notes

The test run still emits the existing jsdom window.scrollTo warning, but the suite passes.
