From Article to Puzzle Loop

The Daily Transit is not trying to separate reading from playing. The article should make the puzzle easier to start.

That gives each Sprint 10 article a job:

1. Name the real-world data source or science idea.
2. Explain what the reader is about to do in one or two plain paragraphs.
3. Link or embed the daily puzzle path.
4. Leave deeper systems and lore out unless they help the action on the page.

This article set uses that shape. One piece explains the Sprint 10 release floor, one explains Close Approach Ranker, and one records the article-to-puzzle pattern itself so the next batch is easier to produce.

The repeatable publication path is intentionally modest: write the article as Markdown, include frontmatter for cards and ticker-like surfaces, validate the CMS shell, and confirm the article routes still build.
