   THE GLITCHMIRE - abandoned digital laboratory
   Structure: warning entrance (#gmWarnScreen) -> glitch-shatter
   transition -> lab hub grid of numbered "experiments" (#gmLab) ->
   click a tile to mount it into a reusable modal stage
   (#gmExpModal / #gmExpStage). Each experiment is a self-contained
   mount()/unmount() pair in the EXPERIMENTS registry inside
   js/biomes/swamp.js (window.initGlitchmire) - new experiments just
   get appended to that array, nothing else has to change.
