Phase Two: Markdown Posts

This post verifies the minimum post system for the second phase.

Posts now live in src/content/blog instead of being written directly as route pages. Pages read these content files and turn them into post lists and detail pages.

The key ideas in this phase are:

• Markdown files store the article body
• frontmatter stores title, description, date, and language
• the file name decides the post slug
• [slug].astro renders different posts with one shared template

Getting this chain working first matters more than adding tags, RSS, or search too early.
