Am I allowed to build and help a website that sells restaurant equipment, including equipment such as wine fridge?

I have a new project as a website developer to build a website for a restaurant supplies business. They sell everything you need for a restaurant (ex: knives, uniforms, shelves, machines) I noticed they also sell things like a wine fridge (empty) and bar equipment like a shaker. Note: they only have a handful of products that might be used for haram (ex: a wine fridge) but it can also be used for halal (ex: to store non alcoholic beverages) I found online source here that if the business doesn't specialise in haram (ex: they specialise in selling alcohol), it is allowed: https://www.islamweb.net/en/fatwa/395065/designing-restaurant-or-hotels-that-may-include-places-for-alcohol But they don't have any specific reference. Not sure what's the ruling here, please help. Thank you
