Never Recovered From An Early Error

Michal Styblo (2185) - Spanton (1864)
Calvià U2350 Round Two
QGD Tarrasch
1.d4 d5 2.c4 e6 3.Nf3 c5 4.cxd5 exd5 5.Nc3 Nc6 6.g3 Nf6 7.Bg2 c4!?
The game has transposed to the Swedish Variation, which has a dubious theoretical reputation

How should Black proceed?

10...Nxe5?
The diagrammed position is reached 2,162 times in ChessBase's 2023 Mega database, with 2,086 games continuing 10...Be6. Komodo14.1 reckons White is then slightly better, but Stockfish16 calls the position equal.
11.dxe5 Ne4?!
Probably better is 11...Ng4, but the engines still much prefer White.
12.Bxe4 dxe4 13.Qxd8+ Bxd8 14.Bxd8 Rxd8 15.Nxe4
White is a pawn up and has a great outpost at d6 for the knight

15...Rd5 16.Rfd1 Be6 17.Rxd5 Bxd5 18.Nc3!?
There seems nothing wrong with the obvious 18.Nd6.
18...Bc6 19.a4 a6 20.a5 Kf8 21.Rd1 Rc8 22.f4 Ke8 23.Kf2 Rd8?!
This speeds the end.
24.Rxd8+ Kxd8 25.Ke3 Bd7 26.Kd4 Be6 1-0
