Clearspace

Minimum clear space equals the height of the "A" in the wordmark. No element, including copy or image content, should encroach on this space.

Usage

Use the SVG version whenever possible.
Maintain the original aspect ratio.
Ensure sufficient contrast against backgrounds.
Use the white variant on dark backgrounds.

Don't

Stretch, distort, rotate, or skew the logo.
Change colors outside the approved palette.
Place on busy or low-contrast backgrounds.
Add effects (shadows, gradients, outlines).

Tone

Plain. Technical. Precise without being cold. No exclamation marks, no emojis, no marketing lift. Read as if the reader already knows what they're doing.
