What Preface shows you
Five layers of context, one highlight away

Every panel is built from the actual sentence you selected — not a generic glossary entry.

Historical Context

How this term, person, or policy got here — the backstory the article assumes you already know.

Implications

What this development actually changes — for markets, policy, or the people it affects.

Connections

How this story links to others — related events, people, and decisions feeding into it.

Market Data

Live yields, indices, and tickers tied to what you highlighted — pulled in real time, not from memory.

Further Reading

Source-linked reading if you want to go deeper than the panel — no dead-end summaries.
