   Nalmeok site

   Breakpoints (mobile-first):
     0–479      small phones, fold cover screens (280–344)
     480–767    large phones, fold inner portrait
     768–1023   tablets, fold landscape
     1024–1279  laptops: two-column hero, sticky section labels
     1280+      wide desktop; the container stops growing

   The page is built from rules, not boxes: sections are separated by
   hairlines, labels sit in a left rail on desktop, and the only filled
   block is the API-key band near the end.
