+# Apparel artwork
+
+Print-ready artwork for the **black** modern-python org t-shirt, generated by
+`brand/build/apparel.py`. Regenerate with:
+
+```bash
+uv run python -m brand.build.render
+```
+
+## Colorway
+
+Two-ink spot print, cream + gold-dark (the on-dark org treatment):
+
+| Token | Hex | Role |
+|-------|-----|------|
+| Cream | `#f4f1e8` | MODERN, top crop, chevron snake |
+| Gold-dark | `#f0b528` | PYTHON, bottom crop, chevron, URL |
+
+## Files
+
+| File | Placement | Print size |
+|------|-----------|-----------|
+| `chest-mark.svg` / `chest-mark-1050.png` | Left chest, standard placement | ~3.5 in wide |
+| `back-lockup.svg` / `back-lockup-2400.png` | Back, centered, ~4-5 in below collar | ~8 in wide |
+
+The transparent chevron mark is `geometry.mark`; the back lockup (wordmark +
+`modern-python.org`) is `geometry.apparel_back`. PNGs are 300 DPI fallbacks;
+prefer the SVGs (vector) for print. Send the vendor a black garment with a
+2-color print in the two hexes above.
