Overview

This design language is a high-contrast engineering system for document intelligence and agent workflows. It uses white space, hard black controls, large rounded-grotesk type, technical tables, and structured gradient objects that look like document stacks or workflow blocks.

Colors

Use white as the main canvas and black for primary text, icons, and CTAs. Use F5F5F5 for section panels and table zones, with E7E7E7 as the rule color. Use orange, pink, cyan, and electric blue only inside structured gradients, metric numbers, selected pricing states, and data-object illustrations.

Typography

Use a rounded engineering grotesk. Top-level headings sit around 60px / 64px with medium weight. Section headings sit around 44px / 52px. Controls and table headers use small uppercase mono or mono-like labels. The type should feel blunt and precise. Avoid decorative serif or soft lifestyle copy.

Layout

Build pages on a white grid with visible horizontal rules. Pair a large technical claim with a structured visual object: stacked pages, blocks, cubes, charts, or tables. Pricing uses tall cards followed by comparison tables. Product pages use numbered sections and split layouts where copy sits beside a diagram.

Core identity and authoring metadata from the refto.one design model.

Gradient Document Stack

A stark white document-intelligence language with hard black CTAs, square navigation, big grotesk headlines, gradient document-stack illustrations, dotted color fields, pricing cards, and comparison tables.

Technical, high-contrast, exacting, and slightly experimental through gradient data-object visuals.

Usage rules
Keep interaction chrome black and white; reserve color for data-object gradients.
Use gradients as structured fields, not loose decorative backgrounds.
Use gray rules and tables to make dense information feel engineered.

Typography Rules

Fields outside the primary renderer remain visible here as structured fallback content.

Rules
Use large black grotesk type with minimal typographic decoration. · Use small uppercase labels for buttons, table headers, and eyebrow markers. · Let contrast and grid placement create hierarchy before adding color.

Layout Principles

Use a white grid with strong black type and clear horizontal rules.
Pair technical copy with a large structured gradient object.
Use tables, comparison cards, and metric rows for proof.
Keep buttons square and direct.
Place gradient fields behind data objects, not behind text-heavy sections.

Iconography

Schema-agnostic optional blocks from the design YAML. New option keys render here automatically.

Summary
Use stacked documents, isometric cubes, tiny square bullets, package icons, and outline data-object marks.

Responsive guidance

Schema-agnostic optional blocks from the design YAML. New option keys render here automatically.

  • -
    Below 860px, stack hero columns and make comparison tables horizontally scrollable.
  • -
    Keep square buttons readable; do not turn all CTAs into rounded pills.

Anti Patterns

Compact list of patterns the design system explicitly avoids.

  • -
    Do not soften every control into rounded SaaS pills.
  • -
    Do not use gradients behind dense text.
  • -
    Do not replace tables and benchmarks with vague marketing cards.
  • -
    Do not add shadows to every surface; rules and grid structure are the main depth system.
