# Prompt: Atlas Cognition "Lab" features section

Build a single-file **product features section for a fictional AI research company, Atlas Cognition**. Use plain HTML, CSS, inline SVG and vanilla JS, with no framework and no build step. The look is a quiet near-black lab: a big serif headline, small mono labels, and a bento of four dark graphite cards. Each card has a softly lit inner panel with a technical line illustration. There are no photos; everything is CSS gradients and SVG.

## Scale

- **Units:** card internals are sized in reference pixels times `--c`, a container-query unit (`100cqw / <card reference width>`), so each card scales as one piece.
- **Desktop (container width ≥ 1164px):** a reworked bento.
  - Environments and Inference are full-width rows, each with the panel on one side and the copy on the other. The two rows are mirrored, so Environments has its panel on the left and Inference has its panel on the right.
  - Evaluations and Hosted Training sit side by side between them.
- **Narrower:** the cards stack in one column with the panel above the copy.
