/* (cl-batch164) Level 1's ladder editor look for the PLC exercise pages. Part 1: the ladder-editor rules of css/trainer.css
   (v=dark1), copied by work-cl164/extract-css.js and scoped with :where(.ct-exl) (the #drill container). :where adds no
   specificity, so this file loads BEFORE css/level1-studio.css and level1-studio.css wins exactly as it does on Level 1,
   while trainer.css's generic class names (.lamp, .small-btn, .branch) cannot reach the rest of the page. */
