Description: A dark, editorial WordPress theme for corporate trainers and consultants. Program thumbnails sit desaturated until you hover, then develop into full color — a small, quiet signature carried over from the theme's original life as a photography portfolio. Includes a Training Programs post type with a Topics taxonomy, an optional Journal (blog), and clean, minimal templates throughout.
