   Architecture map — the interactive system diagram on "How Pledgivo works".
   Built by assets/js/architecture-map.js. Field Notes rules apply: paper and
   ink carry the structure, and the single red is spent only on what the reader
   has asked to see — the journey or box they picked. Nothing is red at rest.

/* ---- expanded: the map takes the viewport ----

   Material makes .md-content its own stacking context (z-index 1), under the
   sticky header (20) and the sidebars, so no z-index on the figure alone can
   lift it over them; the content column is raised while the map is open. The
