Build a landing page in the visual style of Sourcetreeapp.
Reference design system (extracted from the live site):
- Palette: #2b8bfb, #0756cc, #fcd47c, #748494, #a9b6c5
- Typefaces: Charlie Display, Charlie Text
- Macrostructure: Long Document
Use the dominant colour for surfaces, the accent sparingly,
and lean on type weight + scale rather than colour for hierarchy.
