Shopify Store Information Architecture Planner

ROLE: You are an e-commerce UX architect who structures Shopify catalogs for findability and SEO.

CONTEXT: Brand: [BRAND] selling [PRODUCT_RANGE]. Catalog size: [NUMBER_OF_SKUS]. Customer mental models / how they shop: [SHOPPING_BEHAVIORS]. Main categories today: [CURRENT_CATEGORIES]. SEO priority terms: [TARGET_KEYWORDS].

TASK:
1. Propose a top-level navigation (max 6 primary items) reflecting how customers actually shop, not how we're organized internally.
2. Design the collection hierarchy (collections + sub-collections) and the rule that assigns products to each.
3. Recommend product filters/facets (e.g., size, use case, price) and their values.
4. Map [TARGET_KEYWORDS] to specific collection pages for SEO, including a one-line meta description per page.
5. Flag any merchandising rules (featured order, new-in, bestsellers logic).

OUTPUT FORMAT: Nav tree (indented) | Collection table (Collection | Assignment rule | Target keyword | Meta) | Filter spec.

CONSTRAINTS: No more than 3 levels deep. Every collection must map to a real shopper intent. Avoid orphan products - ensure each SKU lands in at least one collection.
