extends Control

# Generalizes ResourceCounter/GasCounter/CargoCounter/GasCargoCounter - one
# hardcoded node plus one script per resource, times two scenes - into one
# row per GameState.resource_types() entry, built at _ready(). A new
# resource added to ResourceDefinitions.ORDER/DEFINITIONS gets a HUD row
# with no scene edit and no new script, the same way ResourceBar and
# ResourceTransferList already pick up a new resource automatically.
#
# Layout mirrors what it replaces: a BANKED column (left) and a FLEET HOLD
# column (right), one row per resource, each row a resource glyph plus a
# digit readout. Banked rows are always visible, even at zero (matching
# ResourceCounter/GasCounter today); fleet rows hide at zero, since that
# hold isn't the player's yet (see CargoCounter's own note on why).
