     COLOR
     Concept: "Regulatory slate" — deep navy as the trust anchor, cyan
     as the signal/action color (calls to mind monitoring + data), with
     warm signal tones reserved for risk/alert contexts.
     Replaces the old yellow+electric-blue with something that looks
     closer to Linear/Stripe/Segment than a consumer promo site.

     One modern sans across the whole site for consistency.
     - Display / UI / Body: Inter Variable (16 weights, tabular figures)
     - Mono (data, code, tickers): JetBrains Mono
     Rationale: Inter is Rightlander's closest-to-current vibe but far
     more consistent; it looks premium at display sizes and legible at
     12px — the B2B SaaS reference (Stripe, Linear, Vercel all ship with
     Inter or close relatives).
