Reframe §1 away from a redesign-of-the-old-plugin narrative and root it in
the real-world problem: coediting a markdown document with a machine is hard

rendered view, opaque machine work). Solution and technical substance stand on
their own; proven patterns reused on merit, not as old-plugin lineage.
