fix: properly credit AHD (Mendeley/Kaggle) + Shifaa (Ahmed-Selem) + Wikipedia + WHO sources. Vionex did not author these corpora; only model weights and methodology are ours.

Polish model card: hook line, live demo link, Shifaa dataset link, BioBERT comparison emphasized, collaborator CTA

write-access probe (will be reverted)

Add professional model card

Upload vioBERT-v3 tokenizer

Upload vioBERT-v3: Arabic Medical BERT
