Adjust Add to Cart Button Size & Carousel Layout Like Reference Web

Hello, I would like to make the following adjustments to my website:

Please resize the “Add to Cart” button on the product grid/listing pages to match the smaller and cleaner button style shown in the reference (screenshot 2).

Adjust the carousel/product slider system to display products in the same compact format as in screenshot 2.

Ensure overall alignment, spacing, and button appearance match the reference for a more modern look.
