Build a landing page in the visual style of Thefutur.
Reference design system (extracted from the live site):
- Palette: #041cdc, #082492, #f54e3f, #7cc27c, #899ec5
- Typefaces: Calibre
- Macrostructure: Feature Stack
Use the dominant colour for surfaces, the accent sparingly,
and lean on type weight + scale rather than colour for hierarchy.
