fix: remove overly-aggressive contrast gate, use coverage-range filtering instead [0.3%-20%]

fix: add morphological skull stripping to prevent models from falsely identifying bright skull boundaries as tumors

fix: add contrast check to reject uniform model output as no-tumor (prevents false positives on healthy brains)

fix: restrict heatmap to tumor contour only + tighten threshold to 98th percentile + cap coverage at 20%

fix: match inference normalization to training exactly (min-max, not z-score)

fix: add BraTS-style preprocessing (z-score norm, skull suppression, brain extraction) so models get input matching their training data

fix: percentile thresholding + NaN protection + focused heatmaps to prevent full-image highlighting

fix: universal topology weight loader + remove broken TransUNet models

fix: smart weight loading - auto-detect format and use load_model for Legacy Keras 2 files

fix: replace dark-pixel MRI check with color-diversity check so real grayscale MRIs pass validation

feat: show styled Invalid MRI notice instead of running models on non-MRI images

fix: save stamped result image even on MRI validation failure to prevent broken card icons

fix: fallback to original image upload if validation returns early without creating results

fix: enforce absolute paths for all static assets to stop 404s

feat: expand comparison results to full-screen width

fix: reset keras naming session and fix 404 image paths

style: change comparison results to horizontal layout with side-scrolling cards

feat: fix confidence calculation + add Compare All Models feature

fix: set proper 224x224 input grid geometry for swinunet decoder graph mathematical precision

fix: hardcode available models to ensure UI lists all 10 options

feat: implement Grad-CAM expert clinical heatmaps and boundaries

Attempt HF sync

feat: bypass 1GB size limit with model aliasing, add natively loaded 10 models

Restore models correctly via LFS

Untrack .h5 models so Hugging Face accepts the code
