/*
 * landing.css — public marketing landing (MKT-37, v4 "Editorial + Chat Vivo").
 *
 * Page-level layout only, loaded solely on the marketing host root. Every atom
 * (buttons, cards, bubbles, chips, badges, brand-mark, form field, typing dots)
 * is a base component from ui.css; this file only composes them into the
 * landing's sections and holds the page-scoped motion. Token-only, so it renders
 * correctly under warm light and warm dark from its first commit. Animation is
 * layered on top of a complete, static final state: with no JS (or reduced
 * motion) every reveal, chat bubble, and marker settles visible.
