OrionBrowser/ProgrammableButtons ? reverse-engineered prompt

Build me a simple open source collection of programmable buttons for the Orion browser, with a few useful ready to import examples and clear instructions for people to use them.

I want buttons that help with everyday browsing, like turning on dark mode, removing sticky page elements, translating a page, applying a nicer readable style to plain sites, copying the current page as a Markdown link, opening a page in the Internet Archive, reading selected text aloud, and a couple of AI powered tools like summarizing a page and rewriting a news article more neutrally.

Make the buttons easy to download and import from a URL or from a file, and include short notes for each one so people know what it does and if they need to add their own API key. If it helps, look up the current Orion button format and docs online so the examples work properly. Keep the layout clean and friendly, with the button files grouped in a way that makes sense for someone browsing the repo for the first time.
