/* DANA Wallet v3: page one-offs only.
   Everything shared (type scale, rhythm, rail, chapter, frames, ledger,
   findings, compare, anatomy, scrubbed video, climax, reflection, modal)
   comes from ../case-study.css; see DESIGN.md. What stays here is the
   wallet's own idea, listed under DO NOT REPEAT:
     - the hero: five shipped section slices fanned beside the Wallet home,
       squaring into one column on scroll (wallet.js)
     - the perforated voucher skin on the research findings
     - the numbered four bets, the exploration groups, the asset gallery
     - the pocket-wave climax edges (inline SVG, filled by the system)

   dana-wallet-v3.css stays in place for the pages that still load it. */
