/* Katalisa Life OS — Listbox (kls-*)
 *
 * Custom select/listbox que substitui visualmente o <select> nativo
 * (a lista aberta do select nativo renderiza com chrome do SO — magenta no
 * macOS — e não segue o DS). Progressive enhancement: o <select> nativo
 * continua no DOM como fonte da verdade (form submit, HTMX, validação).
 *
 * Enhancement só no desktop (pointer fino). Em touch o JS pula e o nativo
 * segue (picker mobile otimizado). Ver static/js/listbox.js.
 *
 * Tokens DS: --bento-bg-card, --bento-border, --bento-shadow-slide,
 * --ds-text, --ds-text-muted, brand #912CEE, --ds-violet-ink (#A855F7).
