Getting the best out of FLUX 3

Put any on-image text in quotes and say where it sits. Keep it under six words.
Attach the packshot and ask for it unchanged; describe the scene around it, not the product.
State the placement's ratio (4:5 for feed, 9:16 for Stories) so nothing gets cropped later.
Name the light and the surface (morning light, marble) instead of adjectives like premium.
