SDKInitOptions.shaperUrl

A self-hosted copy of pdf-shaper.bin (~0.4 MB), the text-shaping binary — self-hosting licenses only, likewise refused with FEATURE_NOT_LICENSED without self-hosting. It is downloaded on the first use of a text tool (Edit Text, Add Text, Text box), which shape the text they write with it: kerning, ligatures and complex scripts (Arabic, Hebrew, Indic). Fetch it once from the store under the shaper folder by Kernstra.assetDigests.shaper. A tool that cannot load it falls back to the font's own character map: the text is still written, without kerning, ligatures or complex-script shaping, and the next use tries the download again; a Text box whose words need a bundled face logs a console warning and is drawn with the standard fonts.
