/*
 * Engineering Edge — homepage carousel (first-party replacement for Elfsight).
 *
 * Look mirrors the retired Elfsight slide: a per-slide gradient/colour band, a
 * type badge, bold title, short (line-clamped) teaser, a "More" button, a figure
 * on the right, and dot indicators. Each slide carries its own `background`,
 * cross-faded on change (two stacked layers). White text is protected by a scrim
 * + text-shadow so a light palette entry can't wash out the title.
 *
 * ee theme tokens (kept in sync with static/ka/ka.css / the spec).
