Hello from Horizon

Placeholder — Horizon’s first weekly update goes here.

This is a placeholder for the Horizon weekly update. Replace this file each Friday with your real post — same format as the Houston update:

• A short intro (what changed this week, in plain terms).
• An architecture figure (drop the SVG in posts/horizon/figures/ and reference it: ![caption](./figures/your-figure.svg)).
• Before / after examples.
• Why we build vs. buy.
• A backlog table.

When you push this file on Friday afternoon, it goes live with the evening release.
