PFM-Scanner-Ringkasan-Scope.pdf/.odt — 20 pages covering the flow, folder map,
ports, how to run each part and from which directory, how login and upload move
data, and what is built versus what isn't.
src/build_ringkasan.py draws its four diagrams as native shapes (same approach as
build_deck.py), crops them to img/ring-*.png, and builds the document in one run.
