Compare a theme by the shopper job it serves and the components shown in the exact SKU. Labels can occupy different shelf roles only when product evidence and the merchandising story are distinct.
Define the shelf job
Choose whether the set is an entry gift, story prompt, repeat-play theme or anchor. Do not invent a market price.
Check visible build language
Request current photos and the piece list. Tie copy to observable elements and never infer accessories from a title.
Keep assortment roles separate
Use different shelf labels and comparison bullets when themes answer different shopper questions. If two products have the same build job and only a color change, treat them as a range decision.

FAQ
Does a theme name prove a different shelf role?
No. The role must be supported by observable components and shopper task.
Can retailers compare piece counts alone?
