Summary: CASETiFY adds Special Set collection to menu

Why It Matters: The brand is grouping products into sets. This usually means they want to increase the average amount of money a customer spends by selling multiple items at once.

What Changed:

• Added a new "Special Set" link to the main navigation menu.
• Removed the "Takashi Murakami x CASETiFY" collaboration link from the top navigation.
• Updated the footer with direct links for Thai, French, Indonesian, and Vietnamese language pages.
