#' Example prompts
#'
#' Returns example prompts spanning clean, injection, PII, secret, agency, and
#' misinformation cases, with at least one example touching each OWASP LLM Top
#' 10 category.
#'
#' @details
#' The example data is a small teaching and testing corpus. It is not a
#' benchmark. `expected_action` records the action the built-in policies are
#' intended to produce for that example under normal rule-based scanning. The
#' rows are useful for package demos, unit tests, and explaining the difference
#' between clean text, redaction candidates, and block candidates.
#'
#' @return A data frame with columns `feature`, `type`, `policy`, `prompt`, and
#'   `expected_action`.
