FontLoader

```
public class FontLoader

                    
```
Downloads and registers custom fonts (.ttf/.otf) referenced by a hosted URL in config.
Any element whose font_family value is a font URL (instead of a built-in family identifier) renders that font — the loader downloads it once, caches it in the app's cache dir, builds an android.graphics.Typeface via AndroidTypeface.createFromFile, and hands back a Compose FontFamily that FontResolver returns.
The file-UPLOAD backend (storing an author-uploaded .ttf → serving a stable URL) is separate infrastructure; this loader works with ANY hosted font URL today.

- Method Detail
  - init
```
 final Unit init(Context context)
```
    Wired from AppDNA.configure so downloads can reach the app cache dir.
  - isCustomFontURL
```
 final Boolean isCustomFontURL(String value)
```
    True when a font_family value is a hosted custom-font URL rather than a built-in family identifier.
  - resolve
```
 final FontFamily resolve(String urlString)
```
    Returns a Compose FontFamily for a font URL once it has been downloaded + built; otherwise returns null and kicks off a one-time background download. Callers fall back to the default family until it becomes available (the next config re-render picks it up from the cache).
