Hello, World

First post. This blog is built with Astro on the AstroPaper theme, customized with an image-card post feed and tag-driven navigation.

Table of contents

How posts are organized

Every post carries one or more tags in its frontmatter, and tags do all the grouping:

• Each tag gets its own feed at /tags/<tag>/.
• The tags page lists every tag with a post count.
• The left sidebar (on wide screens) lists tag groups and all tags with counts. Tags pinned via nav.pinnedTags in astro-paper.config.ts appear there as top-level groups.

Writing a post

Drop a markdown file into src/content/posts/:
