CSV bulk upload

Kaise use karein

1. Template download karo (Excel mein bhi open ho jayega).
2. Columns bharo — name + price zaroori. Category mein slug ya exact name (jaise bangles).
3. Images ke liye public URL do (coverImageUrl / gallery). File upload CSV se nahi hota.
4. CSV yahan upload → preview check → Import.

Simple products only (variants / color matrix CSV mein nahi — woh Edit se set karo). Gallery URLs | ya ; se alag karo.

Mode Create only — existing slug = error Upsert — same slug pe update CSV file
