Categorised Shopify product types for generated signs

Sign Customiser now gives each newly generated Shopify product a product type that matches its sign category. This makes it easier to build collections, shipping rules and other Shopify automations for different kinds of signs.

What’s Changed

• Product types now match the sign - New acrylic, metal, stencil, wooden, aluminium, braille, wood-frame and lightbox products receive their own clear product type.
• Neon remains familiar - New neon products keep the existing Custom Neon product type, so established neon workflows continue to work.
• Existing products stay unchanged - The new product types apply when Sign Customiser creates a product. Products already in Shopify are not renamed.
