Consolidate the card components and font pipeline

Two smaller cleanups that fit the redesign:

• AlbumCard and ArtistCard are ~90% the same structure. Extract a base card (image, title, subtitle, right-hand slot, link target) and make each a thin wrapper
• Fonts are loaded three different ways: @fontsource packages installed but unused, a raw .ttf imported in main.tsx, and an @font-face in globals.css pointing at the ttf. Pick one (fontsource woff2 is the sensible default), delete the rest, and preload the main weight
