Mapbox/MapLibre to CSS Font Utility

mapbox-to-css-font is a focused JavaScript/TypeScript utility designed to convert Mapbox GL Style font definitions, whether single font names or complex fontstacks, into a CSS-compatible `font` shorthand string. The package is currently at version 3.2.0 and is actively maintained, with recent minor releases addressing bug fixes and dependency updates. Its primary function involves parsing Mapbox-specific font declarations and generating a standard CSS font property string, handling details like font size and line height. A key differentiating feature is its intelligent font replacement mechanism, which substitutes common Mapbox/MapLibre fonts (e.g., "Arial Unicode MS", "DIN Pro") with widely available system fonts or open-source alternatives like Arial or Barlow, ensuring visual consistency when the original fonts are not present. It also correctly extracts style and weight from the primary font within a fontstack and applies it consistently.
