def self.usage(program_name = "harnex pane")
  <<~TEXT
    Usage: #{program_name} [options]

    Options:
      --id ID       Session ID to inspect (required)
      --repo PATH   Resolve using PATH's repo root (default: current repo)
      --cli CLI     Filter the active session by CLI
      --lines N     Capture the last N lines instead of the full pane
      --follow      Refresh the pane snapshot every second until the session exits
      --interval N  Refresh interval in seconds for --follow (default: #{FOLLOW_INTERVAL.to_i})
      --json        Output JSON with capture metadata
      -h, --help    Show this help

    Common patterns:
      #{program_name} --id cx-i-42 --lines 40
      #{program_name} --id cx-i-42 --lines 40 --json
      #{program_name} --id cx-i-42 --follow --interval 2

    Gotchas:
      pane requires a tmux-backed session.
      Use --repo when the same ID exists in multiple repos or worktrees.
      Do not use pane state alone as completion proof; verify artifacts/tests.
