/* Design and interactive figures for introducing-behaviorgpt-v4.html, ported
   from the unboxai.com/behaviorgpt page (homepage repo: client/behaviorgpt.css).
   Page styles are scoped under body.launch and figure styles under .bgpt, so
   the rest of the research blog is unaffected. The language-vs-behavior figure
   lays out against its own width (container queries), not the viewport,
   because it sits in a narrower column here. */
