wtf is base16-schemes-source?

Base16 Schemes Source is a registry that collects links to color scheme repositories so that multiple Base16 Builder tools can all access the same set of themes. In practical terms, if someone designs a color palette for code editors or terminal apps and lists it here, that palette becomes available across every tool that builds on the Base16 styling system. Base16 itself is a framework for defining themes in a structured, 16-color format. Rather than each editor or terminal application maintaining its own separate collection of themes, Base16 lets theme authors write a palette once, and then builder tools can automatically convert that palette into the specific format needed by Vim, Emacs, iTerm, or dozens of other applications. This repo serves as the shared source list that builders reference to discover and pull in available color schemes. The people who would use this are theme designers and the maintainers of Base16 Builder tools. A designer who creates a new color scheme would add their repository to this list so that builders can find it and include it automatically. End users of code editors or terminals benefit indirectly, since their preferred application can offer a wider selection of consistently formatted themes. One notable rule is that any color scheme listed here must be released under the MIT license or something more permissive. This keeps the ecosystem open and ensures that builder tools, which often generate theme files for many different applications, can freely bundle and distribute the schemes without legal complications. The README is quite sparse and does not go into further detail about how the list is maintained or what specific builder tools consume it.
