Sign Customiser

Lists the customiser's letter types in the order the storefront presents them (sort_order, then id). base_price is integer minor units of currency, letter_parts is the letter type's own structure, and image fields are read-only public URLs. A cut-out metal or stencil customiser offers no letter types and always returns an empty collection.
