File badge

The mark of a file's type, nol-file-badge, a 1rem box beside the file's name: letters on a tinted rounded square for code, PDFs, documents, spreadsheets and tables of data, and archives, a glyph on a tinted square for scripts, a glyph alone in the type's color for other kinds, and a plain file for a name the kit doesn't know; a folder, when the app says the path is one, has a folder glyph in the plain file's color. The type is found by the whole name, such as Dockerfile or .gitignore, then by the last extension, ignoring case and any folders. It is hidden from assistive technology, since the name beside it is the text, and copies as nothing, not even a line break, so a line it sits in copies whole.
