/* Coldcard hack investigation, "The Coldcard wallet hack: $80M gone in 41
   minutes, and the two-cent clue that wasn't" — scoped under .coldcard-hack.
   Ported from the design handoff (The Two-Cent Clue.html + bitquery-brand.css).
   The handoff's sticky .mast masthead and #prog bar are dropped — the site's own
   header supplies that chrome, and the progress bar is the shared
   .inv-progress-track pattern. Full-bleed wrapper matches the other
   investigation stylesheets. */
