+subject: "Meet the four bars"
+---
+
+Here's what we're making right now:
+
+- **Lavender Oatmeal Bar** — $8. Rolled oats and lavender essential oil. Gentle enough for every day.
+- **Clay & Charcoal Mint Bar** — $9. French green clay and activated charcoal with peppermint essential oil. Running low right now.
+- **Oat Milk & Honey Bar** — $8. Oat milk and local honey, unscented and mild.
+- **Cedar & Sage Bar** — $9. Cedarwood and sage, cold-processed with shea butter. Out of stock while we cure the next batch.
+
+That's the whole lineup — no seasonal drops, no seven-flavor rotation, just a small set of bars we know well and make often.
+
+Next up: why "cold-processed" and "cured for six weeks" actually matter.
