content split + copy audit + css polish: content (news/pages/uploads) moves to the ctao/content repo (build overlays it — two-repo build.sh, link-content.sh for local dev); portal copy trimmed to source-documents-only (dashboard empty states, minimal privacy/disclaimer, no mock badges); css: inverted selection on navy bands, featured-card text-track floor, 44px toc target, mobile search dates on own line, footer link row gap; DESIGN.md rewritten as a short handoff
