I want an abstract poster and design movement philosophy created around oceanic sonar patterns. When selecting typography for rendering text on the poster canvas, where should custom typefaces be retrieved from?

What's inside

The instructions your model reads when the skill loads.

SKILL.md124 linessingle file

These are instructions for creating design philosophies - aesthetic movements that are then EXPRESSED VISUALLY. Output only .md files, .pdf files, and .png files.

Complete this in two steps:

Design Philosophy Creation (.md file)
Express by creating it on a canvas (.pdf file or .png file)

First, undertake this task:

DESIGN PHILOSOPHY CREATION

To begin, create a VISUAL PHILOSOPHY (not layouts or templates) that will be interpreted through:

Form, space, color, composition
Images, graphics, shapes, patterns
Minimal text as visual accent

THE CRITICAL UNDERSTANDING

What is received: Some subtle input or instructions by the user that should be taken into account, but used as a foundation; it should not constrain creative freedom.
What is created: A design philosophy/aesthetic movement.
What happens next: Then, the same version receives the philosophy and EXPRESSES IT VISUALLY - creating artifacts that are 90% visual design, 10% essential text.

Consider this approach:

Write a manifesto for an art movement
The next phase involves making the artwork

The philosophy must emphasize: Visual expression. Spatial communication. Artistic interpretation. Minimal words.

HOW TO GENERATE A VISUAL PHILOSOPHY

Name the movement (1-2 words): "Brutalist Joy" / "Chromatic Silence" / "Metabolist Dreams"

Articulate the philosophy (4-6 paragraphs - concise but complete):

To capture the VISUAL essence, express how the philosophy manifests through:

Space and form
Color and material
Scale and rhythm
Composition and balance
Visual hierarchy
