   DISCOVER SHELL
   Shared by the browse pages people come to spend time on: the NFT marketplace
   and Challenges. Content-first — a sticky tab bar, then media. No stat tiles,
   no page-header block; the mobile app bar already carries the page title.

   Colour follows DESIGN-REFERENCE.txt: neutral ground, magenta for the one
   primary social action, gold only for money, green only for success.
