# NVIDIA — Style Reference
> An engineering-grade marketing system organized around two surface modes — a deep black canvas for hero and footer chapters and a flat paper-white canvas for body content — connected by a single, almost violently saturated NVIDIA Green accent that carries every CTA, every active tab, and the small decorative corner squares that mark out cards. The system is unapologetically angular: 2px radius across every surface, tight bold sans-serif typography in NVIDIA's proprietary EMEA cut, and a hairline gray rule that separates dense multi-column technical content. There is no decorative gradient, no atmospheric mesh, no soft drop shadow — just black, white, gray, and green stacked into a structured editorial grid that scales from product cards to massive industry landing pages without bending its rules.

## Do's and Don'ts

### Do

- Use `--color-primary` for the brand's primary interaction treatment.
- Keep page surfaces anchored to `--color-canvas`.
- Preserve every typography style's documented size, line height, and letter spacing.
- Compare major implementation decisions against [the live NVIDIA website](https://www.nvidia.com/).

### Don't

- Do not introduce colors outside the documented color token set.
- Do not replace `--color-ink` with an arbitrary neutral.
- Do not flatten documented component states or spacing relationships.
- Do not treat this extracted snapshot as newer than the live source website.

## Layout

Use the documented spacing scale and component geometry as the implementation baseline. Validate responsive composition and current page rhythm against [the live source](https://www.nvidia.com/).
