NativeElixirPdfUtilities.HtmlToPdf.FontFallback (native_elixir_pdf_utilities v0.8.0)

View Source

Resolves styled text graphemes to fonts before layout and PDF writing.

The selected CSS face is tried first, followed by the remaining requested families, configured font faces, and the bundled fallback faces. Adjacent graphemes using the same face remain one text node so layout can measure and wrap the final font runs.
