   ChronicSync — Hero Slider
   Bootstrap 5 carousel (fade mode) driving the homepage hero. Slide art is
   built from the site's own CSS-illustrated components (no photography is
   available in this project) so it carries zero image payload; swap in real
   photography later by replacing the .cs-hero-visual markup per slide.
