settings::ThemeEditor lays a theme open: density, corners, text size, high contrast and reduced motion, then twelve colors of the mode shown, each a swatch that opens a picker beside its hex; each change hands the owner a whole draft. Theme::set_palette takes an owner's palette per mode, the colors fading to it when the mode shows; Theme::palette names the palette the shown mode fades to; Palette::token_mut and Syntax::token_mut reach a color by its field's name. The gallery's theme page applies the editor to the whole gallery live, with a way back to Ely's theme.
