Gutter

Leverages a symmetrical layout grid to structure blocks. Wide margins ensure high-fidelity reading focus across viewport transitions.

07 — Guidelines

Design principles

Core behavioral guidelines to preserve the design language's integrity when scaling templates.

Technical grid

Keep cards flat or wrap them in thin blue borders to align elements strictly like code containers.

Electric cyan

Utilize neon cyan highlights for hovered button borders and interactive links.

Structured data

Fira Code provides tabular alignment; utilize monospace numerals for metrics tables.
