Theme Name:         UoM Accounting & Finance
Theme URI:          https://www.uom.gr/acf
Author:             University of Macedonia — Dept. of Accounting & Finance
Author URI:         https://www.uom.gr/acf
Description:        A premium, Ivy League-quality WordPress theme for a postgraduate program in Accounting & Finance. Built with a disciplined Stanford-inspired visual identity (Cardinal Red #8C1515, Sandstone #D2C295), editorial typography (Source Serif 4 + Source Sans 3), and academically serious layouts for Program, Curriculum, Faculty, Research, Admissions, News and Contact pages. On activation, the theme auto-installs all pages, assigns their templates, builds the primary navigation menu and sets the homepage — delivering a complete, ready-to-edit graduate-school website out of the box.
