# The hub and workshop menus name what is left in each vessel they hold.
#
# #216 gave them crews that wear out, and the whole point of that is a
# decision - "build another before this one is spent" - which the player can
# only make if they can read the figure. A bar alone said "getting low"; the
# number says how low.
#
# Covers:
#   A. a hub lists every transporter it holds, worst first, with runs left
#   B. a workshop says REPAIRS rather than RUNS, in its own capacity
#   C. an empty structure says nothing rather than "0 / 0"
