New look: slate-indigo panels, pink accent, Poppins, and a gradient card for your song

Inspired by a dashboard design the user shared.
- App: new palette and fonts, borderless rounded panels with soft shadows, a pink-to-blue
  gradient card for your own song (text and controls switch to white on it), flat cards for
  friends, a 'Hi Chris, welcome back' header, an outline bell, and a pink pill on the active tab.
- Website: the same look, plus a wide-screen layout with a sidebar, the page in a rounded panel,
  and a right column with your profile, recent activity and recent plays. Phones keep the top
  bar and bottom tabs.
