//! Terminal display helpers — mirrors `info`, `ok`, `warn`, `err`, `section`,
//! and `_confirm` from `odin.sh`.

// ── Single-line printers ──────────────────────────────────────────────────────

/// Print an info line: `  ▸ <msg>` in cyan.

/// Print a success line: `  ✔ <msg>` in green.

///
/// Prints `  <prompt> ` and reads a line from stdin.  Returns `true` only
/// when the user types `y` or `Y`.  Any other input (including empty) is
/// treated as "No".

/// The `prompt` string may contain ANSI escape codes; they are passed
/// through unchanged so callers can style the question themselves.
