1885 Output Schema 5f5349ba

# Output Schema

Fill every section below with concrete, implementation-ready values for the target aesthetic. Replace all `[bracketed placeholders]` with exact CSS. Omit nothing — a coding agent will use this as its sole reference.

---

## Template

```markdown
# [Aesthetic Name] Design System

> [One-sentence essence of the aesthetic — what makes it instantly recognizable]

## Identity

### Essential Properties
[List 3-5 CSS properties that are non-negotiable. Without these, the aesthetic fails.]

### Characteristic Properties
[List properties that are common but optional — they reinforce the aesthetic but aren't required.]

### Anti-Patterns
[List properties that actively violate the aesthetic. A coding agent must never use these.]

## Usage Notes

- **Every `[bracketed]` placeholder must be replaced** with an exact value. If a property is not applicable to the aesthetic, explicitly state "Not used in this aesthetic" rather than omitting it.
- **Every CSS block must be complete and copy-pasteable.** No partial snippets or pseudocode.
- **Maintain the heading structure exactly.** Coding agents will search by heading name.
- **Dark mode is not optional.** Every color role needs both light and dark values, even if the aesthetic is primarily dark (provide the dark variant as "default" and a light adaptation).
