The blueprint panel is gone; the side panel column now holds the selected
building panel alone at full height. Saving is Ctrl+C on the current
selection, and picking one for placement is a new frameless modal card grid
opened with Ctrl+V, or handed to directly after a confirmed save.
BlueprintPanel sheds its widget half and becomes BlueprintLibrary: the list,
its disk round-trip, capture, and the T hotkey, with no widget of its own.
MainWindow owns it and drives both dialogs, because ModalPauseScope needs a
GameWorldView and only MainWindow has one. Both handlers hold a single pause
scope and a single dim scope across the save-to-select handoff, so the dim
does not blink and the simulation is not resumed in between.
The two facts a card derives -- the per-type contents summary and the plain
cost total -- go into lib/sim next to captureBlueprintFromSelection so they
can be unit tested; src/ui is off the test include path. They are kept apart
from GameWorldView's placement total, which excludes locked types and
rotate-in-place targets and is a different number by design.
A card's delete icon is a sibling of the card body rather than one of its
children: Qt disables a widget's children along with it, and the delete has
to stay live on an unaffordable card.
