//! UI symbols (markers, borders, etc.)
//!
//! ## Character Set Policy
//! - **Unicode adopted**: For consistency with jj default output
//! - Existing UI (app.rs) already uses Unicode characters
//! - ASCII fallback (theme feature) to be considered in future
//!
//! ASCII alternatives (for reference):
//! - WORKING_COPY: '@' (same)
//! - NORMAL: 'o' or '*'
//! - ROOT: '+' or '#'
//! - CONNECTOR: '|'

/// Change markers in Log View
pub mod markers {
