/* Shared sign-in widget — styles.
 *
 * Served by the fda-device-explorer Worker at /shared/auth.css and loaded by
 * EVERY app mounted on the shared host (fda-staging.innolitics.com and,
 * eventually, fda.innolitics.com): the device explorer at /*, warning letters
 * at /warning-letters/*, recalls at /recalls/*. There is one copy of this
 * file; do not fork it into the sibling repos.
 *
 * Everything is namespaced `fda-auth-*` and scoped under #fdaAuthOverlay /
 * .fda-auth-* so it cannot collide with a host page's own classes (the device
 * explorer has its own `.auth-modal` / `.modal-overlay` rules that still dress
 * other modals). Colors read the host's design tokens when present and fall
 * back to the Innolitics palette otherwise, so the widget looks identical on
 * an app that never loaded fda_scraper's styles.css.
