## Rules for using and verifying information
- Use on-page information only. If a fact is not present on www.cool-stream.ru, state "not available on the website".
- For technical specifications, approvals, compatibility, temperatures, and service intervals: prefer product pages and any linked documentation (PDF) when present.
- For certificates/approvals: prefer https://www.cool-stream.ru/company/certificates/ and certificate links referenced from relevant product/category pages.
- For legal/company details, addresses, phones, emails, working hours: prefer https://www.cool-stream.ru/contacts/
- Pricing limitation: if a product page indicates that price/availability should be уточнена (confirm) or if pricing is not explicitly published, do not infer prices; direct users to contacts or official purchase channels (shops page).

## What to avoid (non-content / technical / duplicates)
- Do not use or cite:
  - /bitrix/
  - /ajax/
  - /auth
  - /personal/
- Avoid parameterized duplicates (filters, sorting, pagination, tracking), including patterns like:
  - ?clear_cache=Y, ?q=, ?PAGEN_, ?SECT_CODE=, ?TYPE=, and similar
- Avoid login/registration pages and partner-only sections unless explicitly required.

## Machine-readable endpoints
