  2. Filter the aisle. Off-species or off-category products were dropped.
  3. Balance the shortlist. We mixed value, premium, size, and specialty picks where the catalog allowed.
  4. Prefer readable product pages. Finalists needed clear photos and size or use guidance.
  5. Rank for buyability. Scores favor clarity and everyday usefulness over hype claims.
