Authsignal
A dark, security-software interface that opens on a near-black hero and resolves onto a warm cream canvas, accented by a single electric periwinkle purple. The system reads as enterprise-grade fintech infrastructure — confident Neue Montreal display headlines, Inter body copy, white pill-ish CTAs, and product UI fragments (passkey prompts, transaction cards) floated over purple feature panels. Brand voltage comes from the periwinkle accent (#8b7bff) and the dark-to-cream surface inversion rather than from decorative color.
