/* Fixed terminal hit targets (loaded after trainer.css and the level CSS).
   trainer.css v5.63 and the dense-terminal loupe magnified the terminal BUTTON on
   hover (2x, or 2.7x on PLC/contactor/relay blocks). A scaled button is a scaled
   hit box, so a hovered terminal covered its neighbours' centres and swallowed the
   next click (e.g. clicking PBK landed on PBU). The button now keeps its real size
   and position in every state; the magnified ring is a ::before halo with
   pointer-events:none, so it is visual only. */
