/* ============================================================
   AlHoot × Hulul — slides.css
   Per-slide layout + animation END-STATES.
   Builder 1 ships S01 (cover). Builder 2: append S02–S16
   below the marker — keep the .sXX-- class prefix pattern.

   Rule of thumb: markup/CSS always describes the slide's
   FINISHED, visible state; js/main.js applies the hidden
   "from" states. With JS off (or reduced motion) every slide
   must read perfectly as static content.
