/**
 * Drive "Ask anything" chatbot widget (prototype). Loaded on top of
 * drive.css — shares its design tokens (--drive-*).
 *
 * Docks into the hero in place of the ticket CTA (Blocks/Drive.php
 * hero_cta()) rather than floating fixed over the page — the toggle
 * reuses .drive-primary-button/--hero so it's visually identical to the
 * button it replaces, and the panel drops down from it in normal flow.

 * Docked mode (drive-chatbot.js, IntersectionObserver): once the hero CTA
 * scrolls past the top of the viewport, the launcher pops out of the hero's
 * document flow and pins to the bottom-right corner instead, shrunk to a
 * compact pill so a permanently-visible button doesn't dominate the page.
 * The panel opens upward from it (bottom-anchored) since there's no room
 * below a button sitting at the bottom of the screen.
