/**
 * HELP AND PREFERENCES ARE IN THE CORNER OF EVERY SITE PAGE.
 *
 * @hanzo/ui's `Corner`, mounted once (app/providers.tsx, components/shell/
 * help.tsx): a `?` at the window's bottom start corner opens one card, Help
 * first (Get help, Docs, Contact us), then Theme and Language. No Currency:
 * hanzo.ai bills in US dollars only. A theme chosen there is the page's and
 * outlives a reload; a language chosen there sets `<html lang dir>`, and under
 * Arabic the corner is bottom-right. The app keeps its account at that corner,
 * so the app draws none; nor does a page whose cookie banner still asks.
 * Measured on the shipped bytes, nothing off this machine answering.
