**Hallmark uses four design genres—editorial, modern-minimal, atmospheric, and playful—to categorize pages and drive visual language, component choices, and motion rules.**

The Hallmark design system, developed by Nutlope, organizes every interface into one of these four **genres**. Each genre functions as a rule-set overlay that determines theme rotation, component eligibility, and even AI-generated voice tone. Understanding these genres is essential for anyone building with or contributing to the Hallmark system.

## The Four Genres Defined

Hallmark's genre system is documented in [`skills/hallmark/SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/SKILL.md) and implemented in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js). Here's how each genre is defined in the source code:

### Editorial

The **default, canonical voice**. When a design brief provides no specialized aesthetic signals, Hallmark falls back to `editorial`. This genre serves as the baseline for professional, content-forward interfaces.

Source: [`skills/hallmark/references/genres/editorial.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/references/genres/editorial.md)

### Modern-Minimal

Inspired by **Stripe, Linear, and ElevenLabs**—clean, grid-based layouts with restrained color palettes and precise typography. This genre emphasizes whitespace, sharp edges, and functional clarity.

Source: [`skills/hallmark/references/genres/modern-minimal.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/references/genres/modern-minimal.md)

### Atmospheric

The **Suno / Runway / dark-AI-tool aesthetic**. Favors depth, tone-on-tone palettes, and softer motion. Atmospheric interfaces feel immersive and mood-driven, often using dark modes and subtle gradients.

Source: [`skills/hallmark/references/genres/atmospheric.md`](https://github.com/Nutlope/hallmark/blob/main/skills/hallmark/references/genres/atmospheric.md)

### Playful

Post-Linear **"soft school"** aesthetic—bright colors, rounded sans-serifs, multi-accent palettes, and bouncy motion. Designed for consumer-oriented products, onboarding flows, and community features.

## How Genre Detection Works in Hallmark

The runtime genre system is **hard-wired** via a mapping table in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js). Each theme maps to one of the four genres, with `editorial` as the fallback:

```javascript
/* — Theme → genre map ——————————————————————————————————
// Each theme belongs to one of four genres — a rule-set overlay that
// skill picks from. See references/genres/. */
const THEME_GENRES = {
  coral: "modern-minimal",
  cobalt: "modern-minimal",
  bloom: "atmospheric",
  midnight: "atmospheric",
  lumen: "atmospheric",
  hum: "playful",
  // …other themes default to "editorial"
};

const theme = getCurrentTheme();                // e.g. "hum"
const genre = THEME_GENRES[theme] || "editorial";
document.querySelector("[data-theme-genre]").textContent = genre;

```

This mapping enables **automatic genre detection** based on theme selection, with the detected genre surfaced in the UI via `data-theme-genre` attributes.

## Genre Detection from Design Briefs

Hallmark includes programmatic genre detection based on keyword signals in design briefs. The logic, mirrored from [`SKILL.md`](https://github.com/Nutlope/hallmark/blob/main/SKILL.md) lines 230–240, works as follows:

```javascript
// utilities/genreDetector.js
import editorial from "./references/genres/editorial.md";
import modernMinimal from "./references/genres/modern-minimal.md";
import atmospheric from "./references/genres/atmospheric.md";
import playful from "./references/genres/playful.md";

export function detectGenre(brief) {
  const lower = brief.toLowerCase();
  if (/\b(fun|consumer|casual|friendly|onboarding|family|community)\b/.test(lower))
    return "playful";
  if (/\b(stripe|linear|elevenlabs)\b/.test(lower))
    return "modern-minimal";
  if (/\b(suno|runway|dark|ai)\b/.test(lower))
    return "atmospheric";
  return "editorial"; // default
}

// Usage
const genre = detectGenre(userBrief);
console.log(`Chosen genre → ${genre}`);

```

The detection prioritizes **specificity**: playful and atmospheric keywords are checked first, with modern-minimal and editorial as subsequent fallbacks.

## How Genres Influence Component Selection

Genres act as **gating mechanisms** for components. Certain components are restricted to specific genres:

| Component | Allowed Genres | Notes |
|-----------|---------------|-------|
| Floating pill | `modern-minimal`, `atmospheric` | Precision UI element |
| Brutal slab | `playful` | Bold, expressive container |
| Editorial masthead | `editorial` | Default header pattern |

Example implementation from [`component-loader.js`](https://github.com/Nutlope/hallmark/blob/main/component-loader.js):

```javascript
const hero = document.querySelector(".hero");
const genre = hero.dataset.genre;

if (genre === "playful") {
  loadBrutalSlab();   // defined in references/components/n7-brutal-slab.md
}

```

HTML structure with genre annotation:

```html
<div class="hero" data-genre="playful">
  <section class="brutal-slab">…</section>
</div>

```

## Runtime Theme Switching with Genre Preservation

When switching themes client-side, Hallmark preserves the genre mapping through the `THEME_GENRES` table:

```javascript
function setTheme(themeName) {
  document.documentElement.dataset.theme = themeName;
  const genre = THEME_GENRES[themeName] || "editorial";
  document.documentElement.dataset.genre = genre; // global CSS hook
}
setTheme("hum"); // → genre "playful"

```

The `data-genre` attribute on `<html>` enables **genre-specific CSS selectors**:

```css
[data-genre="modern-minimal"] .card { border-radius: 0; }
[data-genre="playful"] .card { border-radius: 1rem; }

```

## Summary

- **Four genres** structure Hallmark's design system: `editorial`, `modern-minimal`, `atmospheric`, and `playful`.
- **Editorial** is the default fallback; specialized genres trigger on keyword signals or explicit theme selection.
- Genre detection runs in [`utilities/genreDetector.js`](https://github.com/Nutlope/hallmark/blob/main/utilities/genreDetector.js) using regex patterns matching brand references and emotional descriptors.
- The `THEME_GENRES` mapping in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js) connects themes to genres at runtime.
- Components are **gated by genre**, ensuring visual consistency within each aesthetic territory.

## Frequently Asked Questions

### What happens if no genre is detected?

Hallmark defaults to **editorial**. This fallback is hard-coded in both the theme mapping (`THEME_GENRES[theme] || "editorial"`) and the brief detection logic (final return statement).

### Can a single page use multiple genres?

No. Hallmark enforces **one genre per page** as an architectural constraint. The system routes to a single genre to maintain coherent visual language, though individual components may adapt within that genre's boundaries.

### How do I add a new theme to an existing genre?

Add the theme key to `THEME_GENRES` in [`site/js/main.js`](https://github.com/Nutlope/hallmark/blob/main/site/js/main.js) with the appropriate genre value. Ensure the theme's color tokens align with the genre's defined palette in its reference file under `references/genres/`.

### What's the difference between a theme and a genre?

A **theme** is a concrete color/token set (e.g., `coral`, `midnight`, `hum`). A **genre** is an abstract rule-set that groups themes by aesthetic approach. Multiple themes can share one genre; each theme maps to exactly one genre.
