Rebuilding the Blog with AstroPaper

The previous blog implementation was serviceable, but the presentation felt too heavy for a personal writing space.

This rebuild focuses on a cleaner reading experience:

• a simpler homepage
• a clearer post index
• tag pages instead of query-string filtering
• a calmer typography-first post layout

The new structure is intentionally minimal so it can grow with future posts instead of being tied to product marketing blocks.
