/* ==========================================================================
   Upflexity — site-wide design system
   Carried over from the home page design: Noto Sans / Noto Sans Mono, one
   1240px column aligned with the fixed nav bar, boxed "panel" bookends over
   the neural-sphere backdrop, mono uppercase labels, light + dark themes.
   Every page (public, auth, legal, dashboard, workflow editor) uses these
   tokens — never hard-code a colour in a template; add a token here instead.
