      # ---- Secrets ---------------------------------------------------------
      # IMPORTANT: don't pre-write any of the tool/.*secrets-config.json
      # files. The generator at tool/generate_secrets_config.dart has an
      # early-return if tool/.secrets-config.json already exists (lines
      # 57-63), which then ALSO skips creating the per-module configs (evm,
      # solana, nano, tron, bitcoin) — every cw_* module then fails to
      # compile with "Undefined name secrets.xxx" for dozens of keys.
      #
      # Instead: run the generator first so it creates all configs from the
      # full SecretKey list (with empty defaults), then sed-inject Trocador
      # values into the freshly-generated lib/.secrets.g.dart.
