Short answer
A SKU is one sellable variant — size, scent, pack. Inventory, ads and Blinkit availability are all SKU-level problems, not brand-level ones.
Worked example
Your 200ml shampoo can be in stock in Delhi and listed-but-out-of-stock in Patna. That is a SKU-and-city fact, not a 'shampoo is fine' fact.
