/* ============================================
   How it works — "peek" tablet carousel
   One large centered slide with the neighboring slides cropped at the
   section edges (breaks out of .container on purpose). The tab selector
   above it reuses the .showcase__tabs/.showcase__tab component. Text
   (step count / title / subtitle / description) lives as data-* attributes
   on each .hiw-slide and main.js copies it into the shared intro block
   whenever the centered slide changes — JS also drives the track's
   translateX so the active slide is always centered, rather than relying
   on native scroll-snap (simpler to keep the arrows, the click-to-select
   and the text sync perfectly in lockstep).
