   english.shakespeare.4sh.education — Stylesheet
   Ported from English_Chemistry_Site/css/style.css's alternating-slab
   format (slab-dark/slab-alt, slab-image-left/right), extended with a
   two-image "scene duo" per play and a directional scroll-reveal
   (fade-in from left / fade-in from the opposite corner) inspired by
   bankuratourism.com's Elementor entrance-animation pairing (fadeInLeft
   heading + fadeInDown divider on two side-by-side background-image
   cards). slab-definition/slab-subhead/slab-cta/btn-cta — Chemistry's
   classes for its "hook + provocation" chapter format — were dropped
   here since this site's tales.txt content doesn't use that structure.
