June updates: Features backported to all PRSS themes

In line with our June mini-roadmap, we've retrofitted new features to all PRSS themes. For example:

• "Gallery mode", where large images can be previewed by clicking them.
• Combined theme stylesheet, to enhance both user and developer experience.
• Various bug fixes and parity adjustments.

This concludes our planned improvements for June. For folks that use the official themes, these updates will be reflected automatically upon Publish. Feel free to Preview your changes and enjoy the seamless upgrade.

As always, we are open to your feedback! You can reach out to us through the "About & Help" section in PRSS.
