SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Establishes a consistent visual identity and layout rules to ensure thumbnails and UI assets communicate clearly, maintain brand cohesion, and remain legible at small sizes.

Core Features & Use Cases

  • Typography: Specifies Latin and Japanese font pairings and a clear size hierarchy for title and subtitle scales to preserve legibility.
  • Color & Accessibility: Defines base and accent colors and enforces a minimum 7.0:1 contrast ratio for all text/background pairs to meet high-contrast accessibility requirements.
  • Layout & Tokens: Prescribes safe-zone padding, character placement using the rule of thirds, and the use of configuration-driven tokens for all parameters.
  • Use Cases: Generating thumbnails, producing UI components and CSS styles, and reviewing visual outputs for brand consistency and mobile legibility checks.

Quick Start

Create a thumbnail for the topic "2026 Financial Protocol" using the design-system guidelines and verify typography, contrast, and safe-zone layout are applied.
