Create a basic frontend for an online store using pure Bootstrap that will interact with a ready-made backend via API. The main requirement is to quickly and efficiently assemble functional store pages, focusing on connecting to the API. Visual design is not important; functionality and speed are.
**Pages to be created:**
2. **Category Page:**

- Filtering should dynamically update the product list without reloading the page.
3. **Product Page:**
- Connect product data via API.
- Display complete information: name, price, description, availability, images, specifications.
- Button to add the product to the cart.
4. **Cart Page:**

- Ability to change the quantity of products, remove products from the cart.
- Calculate the total cost of the order.
5. **Checkout Page:**

- Data about ordered products is pulled from the cart.
6. **Order Confirmation Page:**
- Simple page confirming that the order has been successfully submitted.
7. **Menu (burger menu):**
- Connect data for the menu via API.
- Simple burger menu for the mobile version.
8. Header Footer
**Technical Requirements:**
- Use **pure Bootstrap** for layout, without ready-made themes.
- All functionality through interaction with the API.
