josemar-rosa/Portal ? reverse-engineered prompt

Build me a simple internal portal website with a login page, a main home dashboard, and separate areas for admin and a few user groups like CA, chef, COL, and project management. I want it to feel like one shared site with consistent styling, shared scripts, and reusable layout pieces, so the same look and feel carries across the whole portal.

It should include basic pages for signing in, signing out, reports, an access denied page, a not found page, and a coming soon page. The reports section should be able to show and print simple document style output, and it should support Portuguese text cleanly. Please make it responsive, keep the design clean and practical, and set it up so it can run as a normal PHP based site with shared CSS and JS. If anything about the old structure is unclear, look up current docs online if you need to and keep the implementation straightforward.
