/* ============================================================
 * sysgraph.css — redirect stub (2026-06-08 consolidation).
 * ----------------------------------------------------------------
 * sysgraph and syskg were two overlapping system-knowledge-graph
 * surfaces. syskg is now the single canonical one. This stub keeps
 * just enough chrome to render a legible "consolidated, forwarding"
 * pointer on first paint (headless screenshots capture this), then
 * sysgraph.js + a <meta refresh> forward to syskg.html.
 *
 * Flavour kept minimal + on-brand: amber-on-near-black, the same
 * three project fonts. Body text clears WCAG AA 4.5:1.
 * ============================================================ */
