+#!/bin/sh
+# Start bokftui with a credential fetched from a Bitwarden/Vaultwarden item.
+# Runs entirely as the invoking user — no root, no sudo.
+#
+#   BOKF_BW_ITEM   item name (default: bokf)
+#   BOKF_BW_FIELD  custom field that holds the secret (default: the password)
+#   BOKF_BW_KIND   password (default) exports BOKFD_PASSWORD;
+#                  token exports BOKFD_TOKEN
+#
+# Works with the official Bitwarden CLI (bw) or with rbw. With bw the session
+# key is cached in ~/.cache/bokf/bw-session (mode 0600) so the master password
+# is only asked when the session expires or after a logout.
