Serbian translation of the exercise catalog (native Serbian)

Serbian is available in the signed-in part of Ars Respirandi, but the full exercise and education catalog is still in English. We want it in Serbian that sounds calm and precise, not machine-made. You will translate or edit the exercise names, instructions and short explanations, and keep one consistent vocabulary for breathing and body terms. Deliverable: the translated catalog in a shared sheet, plus a glossary of agreed English and Serbian terms. Done means: every string is translated, length fits the screens, and terms are consistent throughout. A breathwork teacher or fluent practitioner can follow every instruction without the English. Must know (mandatory): native Serbian; professional translation from English; health, yoga or wellness vocabulary; spreadsheets or a CAT tool. Nice to have: personal breathing or meditation practice; UI localization; experience with Pravopis Matice srpske.
