Allow host-side env ports in free-form --expose#15
Merged
Conversation
Accept ${NAME} and ${NAME:-digits} on the host side of --expose
(and bare HOST:HOST expansion), so publish ports can be overridden
from the host environment at booth start without baking a fixed
number at config time. Container side stays numeric. Document the
pattern and add unit plus config shell tests.
