/* ============================================================
   Shared page machinery for the walkthrough showcases
   (living-profile, skill, self-audit, generative-agents, mcp).

   Layered on top of showcase.css, which owns the chassis:
   tokens, nav, .wrap, .hero, .region, .panel, .btn, .close,
   .rv reveals, footer. Nothing here restyles those — this file
   only adds the figures those pages build their stories from.

   gbrain and dreams keep their own page-local machinery, so a
   class defined here can share a name with theirs without
   colliding: page <style> always wins over a linked sheet.
