One process per family of UI ranges — 2D/10D, 1Y/2Y/3Y, 10Y/ALL and Custom — each independent: only one is active at a time, so nothing here combines their output. Every process here drills to its own section of 2.1 Assemble range data. Every process also reads market yields live, from CNBC (E5)'s chart-bar feed, for its own primary feed or its own live tip — only Intraday archive (S18) and Yield history (S6) are the fallbacks drawn on the left.
