Best practices
- → Export at the exact pixel dimensions to avoid platform recompression.
- → Keep critical text and faces inside the central 80% — outer edges can be cropped.
- → Use sRGB color space; convert from CMYK or Adobe RGB before upload.
- → Stay well under the 5 MB ceiling; smaller files preserve quality after platform encoding.
