/*
 * Shared rich-content stylesheet.
 *
 * Every renderer of structured rich content — the Tiptap editor content, the
 * application-DOM display (RichTextDisplay / LocalizedStringDisplay / the
 * registration ContentPanel), and the broadcast iframe (SceneSlot.buildHtmlSrcDoc)
 * — links this same file so a saved node looks materially the same while
 * editing and after publishing.
 *
 * Saved structures use an outer `.rich-text-display` class supplied by the
 * renderer, plus the stable descendant classes (.rt-section, .rt-columns, …)
 * and `data-rt-*` attributes that the sanitizer allows. The CSS uses custom
 * properties with fallbacks so a renderer (or a registration content theme)
 * can override brand colors without rewriting saved HTML; explicit inline
 * styles on a node always win over these defaults.
 *
 * This file is linked from the root Remix `links` export and from the broadcast
 * iframe document. Do NOT use a late CSS `@import` to load it: CSS imports must
 * precede ordinary rules and the app stylesheet already contains generated
 * layers and application rules.
