   Gopnik NFT Marketplace — v2 Fusion Lab (Iteration 4)
   All styles scoped under `.mpv2f-*`.  Depends on nft_tokens_v2.css for
   design tokens and nft_marketplace_v2.css for the shared nav / chrome.
   Also reuses `.mpv2a-*` atoms (chips, panel-head, hint, pill) imported
   via nft_marketplace_v2_arena.css where already loaded — but this file
   is self-sufficient for the pieces that matter.
