/* FF V4.4 — Imperial Article Frame
 * Visual-only article enhancement for single posts.
 * Adds an imperial museum frame around article hero/video with subtle motifs,
 * lightweight column edges, low-opacity sculpture silhouettes, and softened
 * mobile ornamentation. No content writes, no SEO changes, no audio changes.
