# ─── Optional dependency preflight ──────────────────────────────────
# requirements.txt deliberately omits a few large, rarely-used packages (see the
# commented block at its end), so the hash-gated sync in update_server.sh can never
# notice one *missing* — it installs what that file lists, and these are not in it.
# A rebuilt venv therefore dropped llama-cpp-python silently, and live translation
# degraded to handing every caption back untranslated with HTTP 200. This asks the
# question that sync cannot: does the venv have what the live config is asking it to
# do? Best-effort and always exits 0 — a missing optional package degrades one
# feature, a start script that refuses to start degrades everything.
# Set STT_SKIP_DEP_CHECK=1 to skip it.
