/*
 * In-page document preview modal for rerouted BuddyBoss documents.
 *
 * SELF-CONTAINED + NAMESPACED (.schdoc-*). BB pages carry NO CIS chrome, so
 * nothing here depends on portal CSS or tokens (same constraint as the register
 * page). Every selector is prefixed .schdoc-* so nothing of ours leaks into BB
 * and — because we never style bare tags globally — no BB/theme rule reaches in
 * (the namespace-collision lesson). ALL inks are dark (navy/slate/teal); the
 * only light surfaces are backgrounds, so the light-ink checker stays clean
 * (no white text on a colour → no whitelist entry needed).
 *
 * The overlay sits above BB's sticky header (z-index ~9990) at 100000.
