O0

O0 establishes a commanding, minimalist aesthetic through stark black and white contrasts and oversized, serif typography for headlines. The interaction is focused on content, with a high degree of content density. The system relies on precise typographic interplay and generous negative space to convey a sense of modern authority, using a light theme with occasional inverse dark sections for dramatic effect. Components are typically ghosted or outlined, allowing content to take center stage. Prioritize stark black and white contrasts for all primary interactive and textual elements using #000000 and #ffffff. Use Times 400 for all headlines and display text, selecting appropriate sizes from the established scale (48-88px) with tight line heights (0.9-1.0). Apply Arial 400 for all body text, navigation, and labels, at 16px or 20px, with line heights tuned for readability (1.15-1.5). Maintain a compact element spacing of 10px where interaction requires proximity without visual clutter. Establish clear section breaks using large vertical gaps (60px) or by alternating background colors between Canvas White and Cloud Mist. Utilize ghosted or text-only buttons and interactive elements, relying on color changes for hover states rather than filled backgrounds. Keep all border-radii at 0px to uphold a sharp, angular aesthetic across UI elements. Avoid using saturated colors for backgrounds or primary interactive elements; color should be used sparingly for decorative accents only. Do not introduce soft shadows or rounded corners, as the system relies on flat surfaces and sharp edges. Do not deviate from the strict typographic pairing of Times for headlines and Arial for body text; avoid using other fonts or weights. Refrain from dense layouts where large section gaps (60px) are intended to create breathing room. Do not use background colors with high saturation or significant chromaticity for any functional UI element. Avoid decorative gradients or complex visual textures; the system thrives on minimalism and solid color blocks. Do not allow internal element padding to grow beyond 10px, as the system emphasizes content density.
