// ── Stop Windows from maximising the wizard ──────────────────────────────────
// Mirror of the same block in ArtMoon's installer — keep the two identical.
//
// On a handheld the wizard opens filling the whole screen with the layout still
// drawn for a small window: artwork at natural size in the top-left, a large empty
// area around it. That is a window MAXIMISED after its layout was computed, not a
// wizard computed too large (which would stretch the artwork to full height). It is
// not the Inno Setup version — it did the same under Inno Setup 6.
//
// Windows only auto-maximises windows that can be maximised, so the fix is to say
// this one cannot: take the sizing frame and the maximise box off it. Setup's wizard
// is not meant to be resized anyway — Inno Setup 7 dropped WizardResizable for
// exactly that reason, which makes this a no-op there and a fix everywhere else.
//
// ⚠️ SetWindowLongW, not SetWindowLongPtrW. Both are exported by user32 on 64-bit,
// but the Ptr variant takes a LONG_PTR (8 bytes) and we build a 64-bit installer
// (SetupArchitecture=x64os), so handing it a 32-bit value is the argument-size
// mismatch Inno Setup 7's release notes warn about. Window styles are 32-bit, so the
// plain variant is the correct one for GWL_STYLE on any architecture.
