/* Intergalactic Space Slugs from Space.
   Palette is the game's own "Atomic pulp" set from Docs/Design/ArtBible.md:
   cream enamel, signal red, polished chrome, teal glass. Hostile red
   (#E03A2F) is deliberately absent: in game it means enemies and harm, and
   it should not be spent on decoration. The world accents (violet, magenta,
   acid green) belong to the worlds, so they stay out too. */
