/* ROYAL ACE STUDIO — design system (23.10.2026)
   One accent only: gold. Night surfaces, hairline borders, large tabular numbers with small quiet labels.
   Type: Segoe UI Variable (Windows 11, offline) -> Inter -> system. Mono: Cascadia Mono / Consolas.
   Loaded by every tool page (hub, cruncher, ROYAL RIG, RTP MASTER) so the whole studio reads as one product. */
