/**
 * XERB0XI0N Encyclopedia — Content Typography
 *
 * Applied automatically inside the `<article class="xr-content">` wrapper
 * produced by `resources/views/xerboxion/_layout.blade.php`. Every topic
 * chapter (Markdown or Blade) is rendered inside that wrapper, so this file
 * carries the entire typographic identity of the encyclopedia.
 *
 * The class is intentionally scoped: the stylesheet is inert outside
 * `.xr-content`, which means a dropped-in chapter inherits the cyberpunk look
 * without having to style individual tags.
 *
 * Authoring guidance
 * ------------------
 *   - Write plain Markdown — headings, paragraphs, lists, tables, code,
 *     blockquotes, images all get styled here.
 *   - For xref links use `[[slug]]` (Markdown) or `@xref('slug')` (Blade);
 *     both resolve to `<a class="xr-xref">` / `<span class="xr-xref--missing">`.
 *   - For richer layouts, drop into Blade and reach for the ambient
 *     `--xr-*` custom properties defined in xerboxion.css.

   ========================================
   The topic "viewer" is a single contained block (header + nav + chapters)
   sitting on top of the neural-network canvas background. Without an opaque
   surface the animated bg renders the prose illegible — so we mirror the
   `.paper-viewer` treatment from xerboxion.css: translucent dark surface,
   cyan border, subtle backdrop blur, soft outer glow. */
