/*
 * BreadDoodle — PDF import UI
 *
 * Deliberately self-contained rather than reusing Excalidraw's own CSS custom
 * properties: those are defined on .excalidraw, and this overlay is a sibling
 * of #root so it can survive the editor re-rendering. Dark mode is detected the
 * same way .bt-home-link does it, by looking for theme--dark from body.
 *
 * Palette matches breadtoasting-theme.css: tangerine #eb7006 on paper #fdf6e3.
