 `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.
 
 Current files in `/assets/`:
-- `volcan_logo_master.png` — primary lockup, 1024×1024 PNG on dark background
+- `volcan_logo_master.jpg` — primary lockup, 1024×1024 JPEG on black background
 
 `/assets/archive/` holds older variants kept for reference:
+- `volcan_logo_master_v1.png` — earlier high-resolution PNG version of the master (2 MB, RGBA)
 - `volan lgo black.png` — alternate black-background variant
 - `volcan logo png.png` — same logo on a white background (alt option)
 - `index.html` — 1-byte stub from the original upload, kept for traceability
