# The craft menu used to spell prices out - "15 ore · 5 gas" - which is three
|

# words of chrome per button on a screen with six of them, and it left the
|
||
|
|
# vessel's own name fighting for the same two lines. Every resource already
|
||
|
|
# has a glyph the resource bar and the transfer list draw; this reuses it, so
|
||
|
|
# a price reads as a number beside a mark rather than as a sentence.

#
|

# Built in code from the costs it is given, so a vessel whose price changes -
|
||
|
|
# or a resource added to the catalog - needs nothing here.
