  "textContent": "Additional observation from separate testing:\n\nThis additional test was performed using text-to-image generation, not image-to-image editing.\n\nIn these separate tests, I observed that portrait-oriented outputs consistently resolved to 1024×1536, while landscape-oriented outputs consistently resolved to 1536×1024.\n\nAt this stage, I cannot state this as a confirmed system-wide rule, because testing is still limited. However, across 4 additional tests of this type, together with the earlier 20+ edit / regenerate tests, all observed outcomes so far appear to collapse into one of these two final canvas sizes.\n\nBecause of that, one possible interpretation is that the current output path may be forcing results into a fixed portrait or landscape canvas format, rather than preserving the original source dimensions during reference-image-based edit / regenerate requests.\n\nI cannot verify the internal cause from the outside, but this behavior may be related to the current failures in preserving the original frame and canvas.",
