   Padding rules:
     - Header bar         → --sp-3 horizontal
     - Sidebar items      → --sp-2 vertical / --sp-3 horizontal
     - Cards              → --sp-4 horizontal / --sp-3 vertical
     - Audio player       → --sp-3 horizontal / --sp-3 vertical
     - Code blocks        → --sp-4 horizontal / --sp-3 vertical
     - Hero section       → --sp-9 horizontal / --sp-9 vertical
