Embed **PillFYI** widgets — drugs, glossary terms, interactive tools, and inline elements — on any website. **7 widget types**, zero dependencies, Shadow DOM style isolation, 4 built-in themes (light, dark, sepia, auto), 2 styles (modern, clean), and live data from the [PillFYI](https://pillfyi.com) database.

Every widget includes a "Powered by PillFYI" backlink and a medical disclaimer directing readers to consult healthcare professionals.

⚕️ **Medical Disclaimer**: All Health FYI widgets include an educational disclaimer. This information is for educational purposes only and should not replace professional medical advice.

## Quick Start

```html
<!-- Place widget div where you want it to appear -->
<div data-pillfyi="entity" data-slug="drugs" data-theme="light"></div>

<!-- Load the embed script once, anywhere on the page -->
<script src="https://cdn.jsdelivr.net/npm/pillfyi-embed@1/dist/embed.min.js"></script>
```

That's it. The widget fetches data from the PillFYI API and renders with full style isolation.

## Widget Types

| Type | Usage | Description |
|------|-------|-------------|
| `entity` | `<div data-pillfyi="entity" data-slug="..."></div>` | Entity detail card |
| `glossary` | `<div data-pillfyi="glossary" data-slug="..."></div>` | Glossary term definition |
| `guide` | `<div data-pillfyi="guide" data-slug="..."></div>` | Guide summary card |
| `search` | `<div data-pillfyi="search" data-slug="..."></div>` | Search box |

## Widget Options

| Attribute | Values | Default | Description |
|-----------|--------|---------|-------------|
| `data-pillfyi` | entity, compare, glossary, guide, search, faq, [tools] | required | Widget type |
| `data-slug` | e.g. "drugs" | — | Entity slug from the PillFYI database |
| `data-theme` | light, dark, sepia, auto | light | Visual theme (`auto` follows OS preference) |
| `data-style-variant` | modern, clean | modern | Widget design style |
| `data-size` | default, compact, large | default | Widget size |
| `data-placeholder` | any string | "Search Drugs..." | Search box placeholder |

## Themes

```html
<!-- Light (default) -->
<div data-pillfyi="entity" data-slug="drugs" data-theme="light"></div>

<!-- Dark -->
<div data-pillfyi="entity" data-slug="drugs" data-theme="dark"></div>

<!-- Sepia -->
<div data-pillfyi="entity" data-slug="drugs" data-theme="sepia"></div>

<!-- Auto — follows OS dark/light preference -->
<div data-pillfyi="entity" data-slug="drugs" data-theme="auto"></div>
```

## Styles

```html
<!-- Modern (default) — clean lines, rounded corners, accent gradients -->
<div data-pillfyi="entity" data-slug="drugs" data-style-variant="modern"></div>

<!-- Clean — minimal borders, utility-focused, data-first aesthetic -->
<div data-pillfyi="entity" data-slug="drugs" data-style-variant="clean"></div>
```

## Web Components (Custom Elements)

As an alternative to `data-*` attributes, you can use native HTML custom elements:

```html
<!-- Custom element form -->
<pillfyi-entity slug="drugs" theme="light"></pillfyi-entity>
<pillfyi-compare slugs="drugs,other-slug"></pillfyi-compare>
<pillfyi-search placeholder="Search Drugs..."></pillfyi-search>

<script src="https://cdn.jsdelivr.net/npm/pillfyi-embed@1/dist/embed.min.js"></script>
```

Use `style-variant` (not `style`) to avoid conflicts with the HTML reserved `style` attribute.

## CDN Options

### jsDelivr (recommended — global CDN, auto-updates with npm)

```html
<script src="https://cdn.jsdelivr.net/npm/pillfyi-embed@1/dist/embed.min.js"></script>
```

### Specific version (production stability)

```html
<script src="https://cdn.jsdelivr.net/npm/pillfyi-embed@1.0.0/dist/embed.min.js"></script>
```

### npm (for bundlers)

npm install pillfyi-embed
