/* ==========================================================================
   Portfolio (/portfolio/). Shared kit: page.css (.pg-*). This file only adds
   what's specific to this page: the browser-chrome frame, the alternating
   case-study blocks, the client cards, the capability matrix and the tools
   groups.
   Plan: design-runs/2026-09-28-site-v3/pages/00-plan.md §2
   Round 2 (2026-09-29): chatgpt design review + triage — see
   design-runs/2026-09-28-site-v3/review/portfolio/{chatgpt,triage}.md. The
   throughline: spend pixels on the evidence (screenshots, ratings), not on
   ornament (stacked frames, pill walls, tall mobile cards).
