+> Cadet, single-line `echo` works for short messages. Real files
+> need multiple lines. Two options:
+>
+> - Multiple `echo` lines, each with its own redirect (use `>>` after
+>   the first one to append)
+> - A *heredoc* — write a whole block in one go:
+>
+>   ```bash
+>   cat > journal.md <<EOF
+>   line one
+>   line two
+>   EOF
+>   ```
+>
+> Write a script that creates `journal.md` containing exactly:
+>
+> ```
+> # Cadet Log — Day 1
+>
+> Today I learned to navigate the shell.
+> Tomorrow I will write code.
+> ```
+>
+> Mind the empty line between the header and the body.
