/* Multi-Strategy Portfolio Construction Under EVAR Constraints — white paper (layout from the research notes).
   Ink editorial plate: the note's own photograph as a navy duotone hero, the breadcrumb set on it.
   Long-form serif reading with heads in the margin and a drop cap; a second duotone plate opens the
   middle of the note (a risk estimate that updates in real time); the risks close as a three-column ledger; the closing line as a
   pull statement; the next-note panel carries the next note's own plate. */
