Description

JSON Security: I added JSON_HEX_APOS | JSON_HEX_QUOT to the json_encode function. If your product names or descriptions have apostrophes (e.g., Gabi's Special Soda), it breaks the JavaScript string and makes the buttons stop working. This fix makes the data "safe" for the browser.

Duplicate Scripts: I merged your two <script> tags into one block at the bottom. Having toggleModal defined twice can confuse the browser, leading to weird behavior where only the first one loaded works.
