Build a landing page in the visual style of Blockstream.
Reference design system (extracted from the live site):
- Palette: #04c3fb, #0a5973, #fcc076, #77acbc, #bcd0dc
- Typefaces: rigid-square, Inter, Arial
- Macrostructure: Feature Stack
Use the dominant colour for surfaces, the accent sparingly,
and lean on type weight + scale rather than colour for hierarchy.
