-// import-flow.js — v2.1.3
-// Fixes:
-//   • require('path') → window.path (global, no require needed, UXP v6.4+)
-//   • fs.createWriteStream does NOT exist in UXP fs — replaced with
-//     fd-based chunked write: fs.open → loop fs.write(fd,buf,...) → fs.close
-//   • os.tmpdir() not documented → use os.homedir() / process.env.TEMP fallback
+// import-flow.js — v2.1.4
+// Root cause of "Cannot read properties of undefined (reading)":
+//   response.body is null when redirect:'manual' is used — that fetch option
+//   is NOT supported in UXP. UXP auto-follows redirects and does NOT expose
+//   manual redirect control. Dropping redirect:'manual' entirely.
+//
+// Download strategy:
+//   response.arrayBuffer() → write entire buffer via fs.writeFile()
+//   Simpler than fd-based chunked write, works for proxy files (typically <2GB).
+//   Progress reporting is approximate (0% → 100% on completion).
