/*
 * header.css — feature "header" (spec 01 §4–§7).
 * Top bar (.app-header), host list button + dropdown, marquee (.app-brand), account button,
 * version toggle, customer-service modal, and the STYLES of #copyToast and #roomLoading,
 * plus the desktop download area.
 *
 * Values are copied from the spec (minified 8-digit hex colours kept). Rule order follows
 * the original stylesheet: several computed-style quirks depend on it (e.g. the early
 * `.app-brand span` rule overriding the marquee glow, `.brand-contact-slide{font:inherit}`
 * resetting the second slide to the system font – spec 01 §4.4 / quirk Q1).
