wp-plugins/charitable — reverse-engineered prompt

Build me a WordPress fundraising plugin for nonprofits that lets me accept donations directly on my own site instead of sending people somewhere else. I want it to feel simple to install and use, with an admin flow where I can create fundraising campaigns quickly, set a fundraising goal, add an optional end date, and choose suggested donation amounts while also letting people enter their own amount.

Please include support for PayPal and offline donations out of the box, and make the campaign pages work cleanly with normal WordPress themes. Donors should be able to view a campaign, donate on site, and help us track progress toward the goal. I also want the plugin to support unlimited campaigns and be built in a way that can be extended later for extras like anonymous donations, user profile photos, or campaign updates.

Keep the experience friendly for non technical nonprofit staff. If you need to, look up current WordPress plugin best practices and donation flow patterns online.
