/* ---------- DIFFUZOOM: the descent (web/DIFFUZOOM.md) ----------
   The pane is a single frame plus a rung rail. Every mark that says an image is
   ESTIMATED is ACHROMATIC on purpose: colourised electron micrographs are an
   established publishing convention meaning "real image, prettified", so a
   tinted badge would read as *photograph, tidied up* to the one audience that
   matters. Dashed border + burned footer, no chroma. Real anchors are
   undecorated — a science app owes evidence that. */
