//! Module: shell output separation.
//! Responsibility: separate successful command output from the next prompt.
//! Does not own: SQL value formatting, canister calls, or query execution.
//! Boundary: appends the shell's blank separator to facade-rendered SQL text.

// Keep successful command output visually isolated so the next prompt or shell
// continuation appears after one blank separator line.
