Design B chosen: bold top-down git tree with three branches.
Second fork nearly at same height as first for balanced 'm' shape.
Applied to logo.svg, favicon.svg, and homepage hero.
Restored clean homepage layout (removed design picker).
- Themes now only override CSS variables (no selector overrides)
- Removed duplicate styles from header.tmpl (just loads Inter font now)
- Cleaned up logo SVG (simpler, no overlapping text)
- Improved home page with proper hero layout and sign-in/explore buttons
- Added detailed README documenting the setup, deployment, and design principles
