Monochrome Era Background Art (Project 6T)

Adds a unique background image to every era in the tech and civics tree, giving them more flavor than the minimalist and rather lifeless line drawings of city centers. Additionally, each era now has different images in the tech and civics tree, respectively. The images are taken from various Civ V and Civ VI cinematic intros (with one image from the AoE4 launch trailer snuck in), converted into a monochrome low-contrast style fit for their use as backgrounds. See gallery for a collection of all 20 images. Requires "Grand Eras". This mod can be used as basis for adding your own background art. See the instructional thread under "Discussions" for more info.
