outline discret muted — semnalizare risc L.142 (declaratie reala ireversibila).
Clase .env-badge-prod / .env-badge-test in base.html; eticheta_env expus ca
global Jinja.

Badge de mediu per rand in _submissions, _coada implicit prin view, _preview_rand,
_trimitere_detaliu, _jurnal. Statusbar (_status.html) aliniat la aceeasi conventie

neatins.

rar_env in exportul de audit (AUDIT_COLUMNS + _audit_rows) si ecou in
GET /v1/prezentari(/{id}). _submission_row_view/_detaliu_ctx/fragment_submissions
duc rar_env pana in template.

tests/test_badge_rar_env.py: badge in lista, audit contine rar_env, GET ecou rar_env.
