+### Available print colors (deck boxes)
+
+The deck-box product has a `colors` array — this drives the **Available print
+colors** swatch grid on `/store/deck-boxes` and the color dropdown in the order
+form. Each entry is `{ name, hex, inStock }`:
+
+```ts
+colors: [
+  { name: 'Midnight Black', hex: '#1b1730', inStock: true },
+  { name: 'Nebula Teal',    hex: '#4f8c84', inStock: false }, // shows "Out of stock"
+],
+```
+
+- **Add a color** → append a new `{ name, hex, inStock }` entry.
+- **Mark a color sold out** → set `inStock: false`. It shows an "Out of stock"
+  label on the grid and drops out of the order-form dropdown automatically.
+- **Remove a color** → delete the entry.
+
+Only in-stock colors are offered in the order form; the chosen color is included
+in the order email. Colors are optional — products with no `colors` array (e.g.
+proxy cards) simply don't show the grid or the dropdown.
+
 The shared **requirements / policies** list is also in this file (`requirements`)
 and is rendered on the storefront, the order page, and required as a checkbox on
 the order form.
