Custom CSS to give linkding a dark, card-based layout

linkding-cards.css

/*
Card-based layout for Linkding v1.43+ (Lit elements)
Adapted from Brett Terpstra's original (MIT License)
Updated for v1.45 HTML structure where:
  - li[ld-bookmark-item] → ul.bookmark-list > li[data-bookmark-id]
  - [ld-bulk-edit] → ld-bookmark-page.active
  - Preview image is now a sibling of .content (not inside .title)
