/*
 * Page Builder styles.
 *
 * Section 1 ("pbx-*" component classes) is what
 * Services/PageBuilder/PageComponentRegistry.cs actually emits on published
 * pages (Views/Pages/Show.cshtml) and what the admin builder's canvas
 * preview (wwwroot/js/page-builder/canvas-renderer.js + ui.js) renders, so
 * both look the same — exactly the same reasoning as form-builder.css's own
 * "fb-*" section. Section 2 is the admin editor chrome only (palette,
 * canvas, inspector, layers, toolbar) and never appears on the public site.
 *
 * Deliberately prefixed "pb-"/"pbx-" (not "fb-") so this file can be loaded
 * alongside form-builder.css without any class collisions — both are
 * included on both _AdminLayout.cshtml and _Layout.cshtml.
