How this paper was set

Halftone photograph: the engineer on a public escalator, looking toward the camera. — The inventor, on the stair — file photo.

Type: Libre Baskerville, Lora, IBM Plex Mono. Ink #1a120c on cream #f6eedc. Radius none. The tree is the repertoire; the scoresheet is the CV; the glass case is mailbox-64 alpha-beta with LEARNED as the masthead eval — PeSTO remains a comparison toggle. Gate C at 50 000 nodes printed −143.1 ±40.5 Elo, 100 games, LLR −2.33. The 2200 on that case is club strength, not a published Elo. No template. Chess is content, never a lock.

Three registers

Photographs real and composed; impressions imagined; the subject is real throughout.

The witnesses

Vitest signs the parts list and the node counts. Playwright walks the paper the way a reader would — deep links, the board, the lightbox. The table below is perft: the move generator's receipt against the published start-position series. If those numbers slip, the engine is lying.
