Refactor PDF generation in make_pdf.sh to streamline the process by removing reliance on textutil. The script now directly converts plain text to PDF using cupsfilter, enhancing compatibility and reducing complexity.

+# Export compliance (encryption)
+
+Apple may require an "Export Compliance" statement upload when submitting to the Mac App Store.
+
+This folder contains:
+
+- `EXPORT_COMPLIANCE.txt`: a template statement (fill-in placeholders)
+- `make_pdf.sh`: a helper to fill the template and generate a PDF you can upload
+
+## Generate the PDF
+
+From the repo root:
+
+```bash
+./build_tools/macos/export_compliance/make_pdf.sh \
+  --bundle-id com.dryark.strawberry \
+  --version 1.2.3 \
+  --developer "Dry Ark LLC" \
+  --contact "support@example.com"
+```
+
+Outputs:
+
+- `build_tools/macos/export_compliance/EXPORT_COMPLIANCE.filled.txt`
+- `build_tools/macos/export_compliance/EXPORT_COMPLIANCE.pdf`
+
+## Important
+
+This template assumes the app uses **only standard OS-provided encryption** (e.g. TLS/HTTPS via system frameworks) and does **not** ship proprietary or standalone crypto libraries.
+
+If you bundle your own crypto library (e.g. OpenSSL) or implement custom encryption, you likely need different answers/documentation.
