As per https://coda.io/d/Acre_d3Vs1FswTQA/Engin-Erdogan-7-16-2024_suOyt#_lux7j:

Change in layout for the popup

• Remove the first sentence (Mezo Points are collected from all Acre deposits)
• Bring the green box text to the top in the place of removed one. We may no longer need a green box there.
• Revise the text to: Acre users participate in Mezo points program automatically as a group.
• Remove the bubble that has Chain Launch date in it
