Got questions about the template? Here are some quick answers.
Absolutely. Everything runs client-side in your web browser. We do not store, track, or transmit your color palettes or files to external servers.
We use the standard W3C formula calculating relative luminance. Ratios above 4.5:1 pass WCAG AA for normal text, and above 7:1 pass WCAG AAA.
Yes, you can copy the pure CSS values, Tailwind config extensions, hex codes, or download the full workspace configuration as JSON.
