/* ─── article-flair.css (iter73) ─────────────────────────────────────
 * Magazine-grade article reading shell. Drop cap, sticky scroll-spy
 * TOC, citation-superscript chips, pull-quote pattern, refined

 * subtle paper texture.
 *
 * Plays nicely with the existing /styles/blog.css article rules —
 * this stylesheet only ADDS, never restyles core typography.
