- keep English (language of the current README)
- reshape into profile sections: what I do, selected projects, professional work, stack, contact
- selected projects: 9 public non-fork repos (was 5), each verified against the repo itself
- fix nutriscan (drop unsupported '100+ countries', add live demo), latebra (drop unsupported 'observability')
- professional work: precision retained only where corroborated (8+ domains, coverage thresholds 80/70)
- all 19 remote links return HTTP 200 (curl -L)
