/*
 * BA Helpdesk — the public pages (2026-10-11): help center, contact form, the customer's
 * conversation page and the website chat panel. Stand-alone (no app.css): it runs under its
 * own enforcing CSP and is framed on members' websites. The accent follows the business's
 * colour (--a, set through the CSSOM by help.js — never an inline style). Light and dark follow
 * the visitor (or the chat's theme setting). Mobile-first; every control ≥44px; inputs 16px.
