//! How is `GP_DIALOG.pak` organised? Testing whether dialog id maps positionally.
//!
//! The dialog table gives name -> id (70 records, `DLG_SELECT_DIFFICULTY` = 2000)
//! and the disc gives a unique four-button build at GP_DIALOG entries 2/3. Nothing
//! joins them. If the archive were laid out in table order, or in id order, the
//! join would be positional — this checks.
