/* learn.css — shared styles for the /learn/* SEO guide pages.
   Keeps the 9 Retatrutide guide pages consistent without duplicating a
   200-line inline <style> block on each. Chrome (nav/ticker/footer/cookie)
   mirrors the rest of the site; the article + buy-grid + guide-card styles
   are specific to these pages. Pair with /assets/cart.css (buy-widget styles).
