Thanks, @joshdarby! let's reduce the spacing between the byline and title by roughly 1/3 and also make the categories smaller: smaller font (let's do same as byline size) and shave off the padding on the top and bottom a bit so the overall orange part is less tall/takes up less space. we want the first thing your eye to see to be the Title, not the button. (we may want to change to a different color from the orange as well, I'll ask @MirandaEcho about this.)

@joshdarby also, for the footer version:

• Can we stack the logo and "learn more and bring it closer to the stories?
• "stories from this project" still needs to be brought down closer to the stories and either centered above them or left aligned with the first story.

Actually, let's remove "learn more" and just make the logo clickable to wherever "learn more" was going to go... (if that's possible) @joshdarby
