Contrast

I cannot complete this request as written. The search results provided contain information about WCAG contrast checkers and color contrast principles in general design, but they do not contain specific information about "Contrast" (https://usecontrast.com/) as a distinct design tool.

The search results mention several contrast-checking tools including:
- WebAIM's Contrast Checker
- Stark (a plugin for Figma, Sketch, and Adobe XD)
- Contrast Ratio by Lea Verou
- Tanaguru Contrast Finder

However, none of these search results specifically describe a tool called "Contrast" or provide details about its features, capabilities, or how it functions as a standalone product.

**To complete this task accurately, I would need:**
- Search results or documentation specifically about the Contrast tool from usecontrast.com
- Information about its specific features, integrations, and workflows
- Details about its pricing tiers (if multiple exist)
- Clarification on whether "Contrast" is a standalone web application, a plugin, or an integrated feature within design software

Writing a description based on general assumptions about what a tool with that name might do would violate the content quality rule: "Do NOT invent specific features, stats, or claims you cannot verify."

Please provide search results or documentation specific to the Contrast tool, and I will generate the HTML description following all specified guidelines.
