Build a landing page in the visual style of Design Maestro | Boost your design productivity.
Reference design system (extracted from the live site):
- Palette: #24c4f4, #c8e044, #234354, #549c6c, #bcc0ce
- Typefaces: system-ui
- Macrostructure: Component Playground
Use the dominant colour for surfaces, the accent sparingly,
and lean on type weight + scale rather than colour for hierarchy.
