+## Assets folder
+
+`index.html` is fully self-contained — every image used by the website is embedded as base64. The `/assets/` folder holds the master logo PNGs for label printing, social media, and business cards. The website does not require these files to render.
+
+Files in `/assets/`:
+- `volcan_logo_master.png` — primary lockup
+- `volcan_logo_transparent.png` — transparent background
+- `volcan_logo_black.png` — black-on-light variant
+- `volcan_logo_cream.png` — cream-on-dark variant
+- `volcan_icon_only.png` — mark only (favicon, app icon, social avatar)
+- `volcan_antigua_final_label.png` — bag label artwork
