/* Scale Marketing · the insights library and its articles, in the site's own idiom.
   21 Oct 2026: loads after /assets/css/site.css and adds only what the library needs:
   the shelf grid, the article measure, the "what if" lines, the "what it adds up to" panel
   and the in-shelf aside. Tokens, nav, footer, contact and motion come from site.css. */
