/* ============================================================
   BURDS NERDS — bn-image-guide.css
   Article-scoped styles for /blog/chatgpt-image-prompts-for-beginners
   (the ten-image ChatGPT guide). Loaded only by that post, after
   bn-blog.css and PhotoSwipe's own stylesheet. Every selector sits
   under .ig (the article) or .ig-pswp (its lightbox), so nothing
   here can reach the photography portfolio or any other page.

   CONTRAST, measured against each element's actual fill:
     Text on --bn-surf uses --bn-text in BOTH themes (15.12:1 light,
       14.53:1 dark). In light mode every other token falls short on
       that fill (the reason bn-blog.css overrides the CTA the same way).
     Captions on --bn-bg use --bn-text-muted (4.94:1 light, 5.15:1 dark).
     The copy button border uses --bn-text-muted: 4.41:1 on --bn-surf
       in light, about 4.6:1 in dark, clearing 3:1 for a control edge.
     The lightbox is always dark, so its caption colors are fixed
       custom properties that mirror the dark-theme tokens.
   MOTION: only color/border transitions; PhotoSwipe honors
   prefers-reduced-motion itself, and the adapter disables its fade.
