wtf is nodebb-theme-harmony?

Harmony is the default visual theme for NodeBB, an open-source forum and community discussion platform. If you've ever visited a forum running NodeBB version 3.0 or later, you've likely seen this theme in action. It's the design that shapes how forum categories, topic listings, and individual conversation threads look and feel for anyone browsing the community. In practical terms, a theme controls the entire appearance of a forum. It determines the layout of category cards, how recent posts are displayed, and the overall structure of a discussion page. The README includes screenshots showing what these different sections look like, giving forum administrators a preview of the clean, organized interface their community members will experience. The design relies on a card-based layout, at least for the categories view, though the README notes that the specific cards shown at the top of the categories page come from a separate add-on plugin rather than the theme itself. Forum administrators and community managers are the people who would interact with this. When someone sets up a new NodeBB forum, Harmony is what they get out of the box, so they don't need to hunt for a design or build one from scratch. It provides a polished, modern look immediately, letting the community focus on conversations rather than customizing a layout. For communities that want a reliable, well-maintained appearance without design overhead, this serves as a solid starting point. The README is sparse on technical specifics. It doesn't detail the underlying architecture or customization options, so anyone curious about modifying the theme would need to explore the code directly. Bug reports and issues aren't tracked here either, they're handled through NodeBB's main project repository, which makes sense given that this theme ships as part of the core package rather than as a standalone third-party download.
