//! Shared Markdown hard-break detection for paragraph flushing.
//!
//! Both the stable tail-reflow path and the spanning-code fallback need to know
//! whether a line already ends with a hard break before appending one. This
//! helper centralizes that parity check so the two paths stay consistent.

/// Returns the byte length of the trailing Markdown hard-break marker on `line`.
///
/// A hard break is either two trailing spaces (marker length 2) or an odd run
/// of trailing backslashes (marker length 1). Any other ending, including an
/// even backslash run or no marker at all, returns 0.
