/* Parity Finance. Design tokens.
   Brand is fixed by the approved avatar/banner: one saturated hot magenta, black line art.
   Corporate register comes from the SECTION RHYTHM, not from softening the brand:
   ink token bar, white sticky header, full-bleed magenta hero, paper and mist article
   sections, ink calculator slab, magenta closing band, ink footer.
   Pattern reference: ui-ux-pro-max "Real-Time / Operations Landing" (hero with live
   status, spec row, how it works, CTA). Its style/palette recommendation was overridden:
   the brand identity is locked.
   Type:  Sora 600/700/800  headlines and the wordmark (geometric, heavy, real presence)
          Inter 400/500/600/700  body and UI
          IBM Plex Mono 500/600/700  every number, ticker, CA, gauge, table figures
   Spacing scale: 4 8 12 16 24 32 48 64 96 px.  Radius: 4px chrome, 6px cards, 999px pills.
   Motion: one idiom, a 220ms cubic-bezier settle used by the needle and by every hover. */
