FONT_FAMILIES = Font family lists shared by the SVG output and the Pango-based text measurement. Each entry is an ordered list of family names; the FontFamily helpers format it for SVG (quoted) or for Pango::FontDescription#family (unquoted). Keeping a single source guarantees that measurement and rendering resolve through the same fallback chain.
