Heroku not optimizing stylesheets in Create React App (CRA) hosted with Node

After building my files locally, I noticed that my css folder and its contents are minimized under /build/static along with a js folder and media folder beside it.

However, once I push the changes to Heroku and access my app, the css folder seems to be missing. Instead, within the <head> section of my HTML, I see multiple <style></style> tags. Additionally, in the <body>, there are minified scripts present.

Upon inspecting the sources tab in dev tools, I observed that under static, all I could find was a js folder and a media folder - unlike the structure when I build locally.

It is worth noting that my css files are located within my components, under the src folder.

I am puzzled by this behavior and seeking advice on why this discrepancy occurs and how it can be resolved.
