Layout

  ripdiff  [repo: myproject]   main  3 files changed  mode: inline  panel: files
  M src/main.rs  +5-2 │ src/main.rs
  A src/lib.rs   +3   │
  M README.md    +1-1 │   fn main() {
  ? new_file.rs  +12  │ -     println!("old");
                      │ +     println!("new");
                      │   }

• 25% left: file list with status indicators (M/A/D/R/?) and stage markers (● staged, ○ unstaged, ◐ mixed)
• 75% right: diff output with scrollbar
• h opens a help popup with keybinding and symbol descriptions
• Minimal borders — just a vertical divider between panels
• Auto-refreshes on .git/index changes and every 500ms
