- Use 'Pitch Black' (#08090a) for the primary page background to establish the dark theme.
- Apply 'Porcelain' (#f7f8f8) for all primary text and important icons to ensure readability.
- Highlight primary interactive elements exclusively with 'Neon Lime' (#e4f222) as a background, restricting its use to guide user attention.
- Create depth and hierarchy by layering surfaces using 'Pitch Black' (#08090a), 'Graphite' (#0f1011), and 'Deep Slate' (#161718) backgrounds.
- Employ the Inter Variable font family with specific letter-spacing adjustments for all UI text, such as -0.22px for display sizes and -0.11px for body text, to maintain a tight, precise feel.
- Do not introduce additional bright or saturated colors beyond 'Neon Lime' (#e4f222) for interactive elements; maintain its singular role.
- Avoid using harsh white backgrounds or light-themed patterns, as the system is anchored in a dark mode aesthetic.
- Do not deviate from the specified typeface choices; 'Inter Variable' and 'Berkeley Mono' are fundamental to the visual identity.
- Refrain from using strong, diffuse shadows; elevation is achieved through subtle layering and sharp, contained shadows like rgba(0, 0, 0, 0.4) 0px 2px 4px 0px.
- Do not apply broad, decorative background gradients across large sections of the UI; gradients are subtle and contained to specific functional areas.
