Design system philosophy
fix(design-system): add dated Correction callouts to 12 of 15 design-system/ articles — fabricated --ps-* CSS variable family across 3 articles, stale token counts across 3 more, a shipped-then-removed MCP endpoint, and a WCAG AAA overclaim already corrected once in the real source; 3 verified clean

(Correction, 2026-08-02: no `/mcp` route or MCP module exists in the current `app-privategit-design` build — `grep`/`find` for MCP code in the crate return nothing. Git history shows an MCP endpoint with 4 tools *was* added at one point but is absent from the current checked-out HEAD — a shipped-then-removed feature, same pattern as the deleted collab feature found repeatedly elsewhere in this corpus. This same claim recurs at "the same MCP endpoint" further down and in this article's own See Also section — all three references are affected. Flagged, not resolved.) ## Three structural inversions of the Enterprise-tier pattern
