Theme Name: WesSciJo — Hybrid A
Theme URI: https://wesleyan.edu/
Author: Olayinka Vaughan
Description: Hybrid concept A for The Wesleyan Science Journal. Black title band at poster scale over a red slab that hinges into a white index, then Brutalist structure with the typography reset in Libre Franklin. Mass comes from the setting rather than a display face.
