Brand Identity
The golden ratio appears in spiral galaxies, hurricane eyes, and the proportions of the Parthenon. Our identity draws from the same convergence — minimal, mathematical, inevitable.
The Mark
The lowercase phi (φ) is the sole symbol. Set in Source Serif 4 SemiBold Italic, it carries the weight of mathematics and the elegance of classical typography.
Product Logos
Product extensions append to the phi mark. The suffix uses the same typeface at a slightly reduced size, maintaining the golden ratio in scale.
Clear Space
Maintain a minimum clear space equal to the height of the phi descender around all sides of the mark. The ratio is not negotiable.
Typography
Two typefaces. One for identity, one for interface. The contrast between serif warmth and mono precision mirrors the project itself.

Black and white. No accent colors. The absence of color is the identity — everything converges to the essentials.
Usage
Like the ratio itself, the rules are simple and absolute.
Use the mark on solid black or white backgrounds with sufficient contrast. Maintain clear space. Let it breathe.
Never place on busy backgrounds, apply effects, rotate, recolor, or distort. The mark is not decorative — it is structural.
The Fold
The fold is the interconnected surface of phi — two products woven into a single continuous topology. Like a fold in space, everything within it is closer than it appears.
Everything within the fold converges.
Corner Frame Accents
Fixed-position corner accents frame the viewport on every page. They anchor the layout and reinforce the structural identity of the brand.
