Mercury

The design feels like a command center at twilight, expansive and focused. A deep, near-black neutral palette (#1e1e2a, #171721) creates an immersive, cinematic canvas where glowing off-white text (#ededf3) provides crisp clarity. All energy is channeled into a single, vibrant violet-blue accent (#5266eb) reserved strictly for primary calls-to-action, like indicator lights on a high-tech console. The typography is a defining feature, with custom fonts used at light weights for headlines, creating an authoritative yet approachable voice. The contrast between spacious, atmospheric hero imagery and the stark, text-driven UI below creates a journey from aspiration to action. Use 'arcadiaDisplay' at a light weight (360) for all major headlines to maintain an airy, sophisticated tone. Reserve the 'Mercury Blue' (#5266eb) accent exclusively for primary, action-oriented CTAs. Employ the deep neutral palette (#171721, #1e1e2a) for all backgrounds to create a focused, immersive environment. Utilize extreme corner radii (32px, 40px) for all primary and secondary buttons, creating a signature 'pill' shape. Maintain high contrast with 'Starlight' (#ededf3) text on dark backgrounds for all primary content. Use generous vertical spacing (80px+) between content sections. Differentiate interactive list items with a simple 1px bottom border in 'Lead' (#70707d). Don't use 'Mercury Blue' (#5266eb) for text, backgrounds, or decorative elements. Don't use heavy font weights (>530) for any typography. Don't apply shadows for elevation. Use color and opacity shifts instead. Don't introduce new saturated colors. The palette is monochrome plus one blue accent. Don't use small corner radii on buttons. They should always be pills. Don't use 'Pure White' (#ffffff) for body text; reserve it for text on the primary blue CTA. Don't create dense, cluttered layouts. Prioritize breathing room.
