/* Boxha Boox — legal document shell stylesheet.
   Ported from the approved wrapper preview (warm-gold accent, system-sans, dark/light via
   prefers-color-scheme). Production adaptation: the preview's two-language toggle (buttons +
   [hidden] + inline JS) is replaced server-side — the shell renders exactly one <article> per
   request, and the language switch is two plain anchors (?lang=es / ?lang=en). No JS ships here;
   CSP on the rendered page forbids inline <style> too, hence this external file. */
