/* FaultLine — Research page.
   Self-contained: brand tokens are DEFINED HERE (no dependency on landing.css) so
   this page matches the reframed landing exactly — 90s-clean monospace, the ⊢
   turnstile mark, ONE brand color (electric green = verified / true / terminal-go).
   Dark-first identity + an airy "Cloud Dancer" light mode, WCAG-AA contrast, a neon
   micro-glow on accents/CTAs. Light/dark toggle only — the brand is LOCKED to green,
   no accent picker on marketing pages. No external fonts/scripts/CDNs. */
