The center column is gone: Confirm + Clear move onto the tab sub-bar
([tabs] | [Clear][Confirm] | NET value), serving both the trade and
buyback tabs, so the two panels sit side by side with just a bit of
padding between (grid.centerW 208 -> 16). The row description keeps the
smaller font, word-wraps inside the text column (wrap width stops
before the price), and the char-count budget now spans two lines so the
headless path stays bounded; rowH grows 64 -> 72 to fit both lines.
The buttons persist across tab switches (they were content before and
died with it), Confirm stays grayed while the trade is invalid, and the
stub gains setX/setY so the bar layout is testable.
