Language convention

This repo is deliberately bilingual.

• English: README.md, CLAUDE.md, notebooks, ADRs.
• French: docs/providers/ (catalog, per-provider docs), docs/wasabi/ (state, sync history, anomalies), docs/cal/ (materialized from CAL's French gdrive docs).

The Master program is international (English-first for onboarding), but provider negotiations, data operations, and CAL's source documents are in French.

When adding new content, match the language of the surrounding directory.
