Issue Description: Localized "Sideline" Category Filtering
This feature request aims to enhance the user experience by introducing a region-specific filtering system within the Thailand market. Currently, users in diverse locations—ranging from the bustling streets of Bangkok to the quiet coastal areas of Phuket—require a more granular way to discover relevant profiles. Implementing a localized filter will allow for better matching and a more organized interface, ensuring that the platform remains the most efficient choice for social discovery in Southeast Asia.
By integrating this update, we can significantly improve the discovery process for those exploring the sideline community in specific provinces. Users on fiwfan.app should be able to toggle between regions such as Central Thailand, Pattaya, and Isan to find connections that are geographically accessible. This technical enhancement not only boosts user retention but also strengthens the site's SEO by creating more relevant, location-based landing pages that cater to the specific search habits of the local Thai population.
