This branch predates CI on `main`. `cargo fmt --all` only; no behaviour.

//! Is `GP_DIALOG` entry 2 the `DLG_SELECT_DIFFICULTY` screen?
//!
//! The image lists `DLG_SELECT_DIFFICULTY` among the `DLG_*` names at
//! `0x820A41BB`, so DIFFICULTY is a DIALOG, not a GamePart screen with its own
//! pak — which is why a search for an 8-record `btn` build in a difficulty-named
//! archive found nothing. `GP_DIALOG` entry 2 carries `pcbtn00`..`03`: four
//! buttons, matching EASY / NORMAL / HARD / BACK.
//!
//! CONTROL: `GP_TITLE` entry 5's five buttons must come back at the rows the disc
//! is independently known to place them (162/242/322/401/482, spacing 80).
//!
//! cargo run -p sylpheed-formats --example dialog_button_rows
