This design system projects a direct, no-nonsense corporate voice, stripped down to essential communication. It uses a stark achromatic palette of black and white, punctuated by subtle gray accents to define secondary text and structural elements. The complete absence of visual flair—no shadows, gradients, or rounded corners beyond a minimal 3px—communicates efficiency and seriousness, while the custom 'adineue' typeface offers a distinct, yet understated, brand presence. Use Pitch Black (#000000) for all primary text, headings, and interactive button backgrounds. Maintain a minimal border-radius of 3px for all interactive elements like buttons and input fields. Apply adineue for all headline and body text, ensuring a consistent brand tone. Utilize 40px of vertical margin for significant section breaks and larger content blocks. Employ the 1.4 line height for adineue body and heading text for comfortable reading. Use Absolute Zero (#ffffff) as the primary page background and for input field backgrounds. Apply Concrete Gray (#999999) only for secondary, less prominent text or muted borders. Avoid using any colors outside the defined achromatic palette of Pitch Black, Absolute Zero, Shadow Play, Concrete Gray, and Pebble. Do not introduce any drop shadows or complex elevation effects; the design relies on flat separation. Never use rounded corners exceeding 3px; maintain the sharp, angular aesthetic. Refrain from introducing decorative gradients; stick to solid color fills. Do not deviate from the specified font families (adineue, Arial) or their assigned weights and sizes. Avoid introducing images or graphics with vibrant colors; all visuals should either be monochromatic or integrate seamlessly with the achromatic theme. Do not use letter spacing other than 'normal' for any text elements.
