/* brycejurss.com · home identity stylesheet
   Brand: BRAND/brycejurss-home.md. Warm founder site: cream ground, copper accent, Instrument
   Serif display, Geist body, IBM Plex Mono labels. Depth from hairlines, soft radii (6px),
   restrained motion. A warm dark scheme follows the OS and a toggle. Distinct from the cool,
   deep-blue BJ Research identity at /research: siblings, not twins. */
