More graphical finesse: own beds per creature, animated room furniture, treasure chests, elaborate core and portals, worn floors

- props.rs: furniture drawn near the camera every frame
  - beds built by each creature on arrival, matching its kind (straw, web, starry cushion,
    fur pile, chain bunk, ember cushion, rock hollow, camp bed); gone when the owner is
  - training: spinning dummies, weapon racks, wobbling targets; torture: turning wheel,
    iron maiden, brazier with glowing coals; temple: altar with candles and fire bowl,
    candle stands; library: book shelves, lecterns with floating books while studying
  - treasure chests in the treasury, closed when empty, filled with their treasure otherwise
- Soul core: stepped obsidian pedestal, four spikes with energy threads, circling runes,
  unsteady pulse when hurt
- Portals: circle of standing stones with runes, column of light and rising sparks
- Floors: cracked, chipped and shattered stones, grit and crack decals
