Guide Krea 2 with reference images and training-free concept sliders: stack up to 12 guide cards using plain-language recipes - keep the subject, borrow style/palette/lighting/material, copy pose or shapes, avoid text/logos - write your own recipes, and dial any attribute you can name from -6 to +6 with slider cards. No LoRA training or extra weights.
