/*
 * Form Builder styles.
 *
 * Section 1 ("fb-*" component classes) is shared between the public form
 * output (Services/FormSchemaRenderer.cs) and the admin builder's live
 * canvas preview (wwwroot/js/form-builder.js) so both look the same.
 * Section 2 is the admin editor chrome only (palette, toolbar, properties
 * panel) and never appears on the public site.
 * This file is self-contained (its own custom properties) so it works
 * standalone on the public storefront, not just inside the admin panel.
