/* tiptap-editor.css
 *
 * Tiptap / ProseMirror editor chrome for the shared JadedSoftware.UI TipTapEditor +
 * OutlineEditor components. ProseMirror ships no base stylesheet, so everything the
 * editor needs lives here. Theme-aware via MudBlazor palette custom properties
 * (--mud-palette-*), so it adapts to whichever host links it.
 *
 * This file is the plain-CSS form of WritersBlock's _tiptap-editor.scss: SCSS design
 * tokens ($space-*, $radius-*, $font-*, $shadow-lg, $z-popover, $transition-fast) are
 * resolved to their literal values; every var(--mud-palette-*) reference is preserved.
 * The toolbar / slash-menu DOM is built by JavaScript, so this is a globally-linked
 * stylesheet (a scoped .razor.css would never reach those elements).
 *
 * Consumers link it once, e.g. in the host App.razor:
 *   <link href="_content/JadedSoftware.UI/css/tiptap-editor.css" rel="stylesheet" />
