June 2025 monthly summary for tidyverse.org: Delivered a targeted fix to the front-page visual asset display, correcting the image scaling script and hex image directory path to ensure assets render correctly across devices. The change stabilizes homepage visuals and reduces rendering glitches, contributing to a more professional first impression and lower post-deploy support. The work was completed as a focused fix tied to issue #740 and included in a single commit, enabling straightforward QA and rollout.
