lab.html: 9273 → 5180 lines (-44%)
frontend/js/labs/lab-init.js: new file, 4098 lines
All 34 _open*() functions + sim instance vars + openSim/closeSim/
_addTouchSupport/_simShow + THEORY data extracted to lab-init.js.
Shared globals (FN_COLORS, ALL_SIM_BODIES, ALL_CTRL_BARS, sim vars)
converted from const/let to var for cross-script accessibility.
Three vars in lab.html made global: _disabledSimIds, _theoryOpen, _embedMode.
Load order preserved: lab-init.js added before main <script> block.
