Summary

• Reworked the docs landing page into a more polished, Vercel-style experience with a centered hero, improved command block, a full-width simulator screenshot, and a timeline-based features section.
• Added themed hero background assets and scroll behavior so the background acts like a slow-moving camera instead of a sliding layer.
• Tightened the docs chrome by refining nav/sidebar borders and simplifying the navigation surface.

Testing

• Built the docs site successfully.
• Verified the landing page in the local browser across scroll states and checked that the hero background, nav treatment, and screenshots render correctly.
• Not run (not requested): automated unit or integration tests.
