Research direction

Start by reproducing the reported behavior through createPDFStream and createWriteStream on node-canvas 4.0.0-rc3 with Node v20.19.0 on Linux, using many text-to-PDF conversions. Compare PDF size and write speed, then identify the regression and add coverage for the corrected behavior; the issue does not name specific files or tests.
