#164

What to build

Make product-detail reassurance specific and verifiable. Remove duplicated availability, correct visible Mongolian copy, label dose claims precisely, replace generic trust labels with real import, delivery, packaging, and return information, and describe related products without implying unsupported personalization.

Acceptance criteria

• Availability appears once and agrees with the add-to-cart state.
• Таньд таалагдаж магадгүй is corrected to Танд таалагдаж магадгүй.
• Dose highlights state whether they are per capsule, serving, compound weight, or elemental amount.
• Generic labels such as Баталгаатай and Найдвартай are replaced by specific facts or removed.
• Related products use accurate copy such as Ижил төрлийн бүтээгдэхүүн unless genuine personalization exists.
• Heading structure contains no empty headings and remains logical for assistive technology.
