       LETTER PILE  (added 2026-05-20, replaces wood-grain carousel)
       A real-world pile of letters on a writing desk:
         • Newest letter on top.
         • Cards behind peek out with subtle offset + blur depth.
         • Action bar (Reply / Legacy / Delete) is always visible.
         • Tap = trigger the cinematic ceremony in bond-ceremony.js.
       This block is self-contained — none of the rules above target
       any `.bond-pile-*` selectors, so the new styles never conflict
       with the legacy stack-view rules.
