{{/* 
This partial returns raw SVG content for icons, designed for Preact component integration.

PURPOSE:
- Provides SVG strings that can be passed as props to Preact components
- Enables dynamic icon rendering in client-side Preact blocks
- Mirrors get_icon.html logic but returns raw content instead of safeHTML

DIFFERENCE FROM get_icon.html:
- get_icon.html: Returns safeHTML for direct template rendering in Go HTML templates
- get_icon_data.html: Returns raw SVG string for JavaScript/Preact component consumption

USAGE:
{{ $icon_svg := partial "functions/get_icon_data" (dict "name" "arrow-right" "pack" "hero") }}
Then pass $icon_svg as a prop to Preact components for client-side rendering.

ICON PACK HANDLING:
1. Hero pack (heroicons): Assembles <svg> wrapper around "body" content using pack "height"
2. HB/Brands packs: Returns stored SVG strings as-is  
3. User assets: Returns content from assets/media/icons/{pack}/{name}.svg
4. Fallback: Returns Hugo brand icon if not found

PARAMETERS:
- name: Icon name, optionally with pack prefix (e.g., "arrow-right" or "hero/arrow-right")
- pack: Icon pack name (defaults to "hero" if not specified in name)
