/* ============= CONSTELLATION — a career mapped as the night sky ============ */
/*
   Design grammar (lab study 08):
   • Full-height sky hero: deterministic starfield + labelled SVG constellation
   • Cormorant Garamond display serif, mono micro-labels, hairline discipline
   • Observation-log biography, star-chart register, circular telescope plates
   • Everything token-driven — reads as a printed star atlas on light palettes,
     an open night sky on dark ones.
   All selectors scoped to .pg-constellation.
