Adobe font-face declaration fails to generate in @nuxt/fonts 0.12.1 (regression from 0.11.4)

Bug Report

Describe the bug

Upgrading from @nuxt/fonts 0.11.4 to 0.12.1 breaks Adobe font generation. The module fails to produce font-face CSS rules for Adobe fonts during build, resulting in a warning and fonts not loading.

Warning message

[@nuxt/fonts] WARN  Could not produce font face declaration from adobe for font family Forma DJR Text.

Steps to reproduce

1. Install @nuxt/fonts 0.12.1
2. Configure Adobe fonts with valid credentials:

fonts: {
  families: [
    {
      name: 'Forma DJR Text',
      weights: [400, 700],
      styles: ['normal', 'italic'],
      provider: 'adobe',
    },
  ],
  adobe: {
    id: ['YOUR_ADOBE_PROJECT_ID'], // Your Adobe project ID
  },
}

3. Run npm run build
4. Check the build output for warnings

Expected behavior

Font-face CSS rules should be generated correctly and the font should load on the frontend, as it did in 0.11.4.

Actual behavior

• Warning: "Could not produce font face declaration from adobe for font family Forma DJR Text"
• Font does not load in the application
• Build completes but with warnings

Environment

• @nuxt/fonts: 0.12.1 (regression from 0.11.4)

Workaround

Downgrading to @nuxt/fonts 0.11.4 resolves the issue.

Additional context - Tailwind v4 CSS config

The project uses Tailwind v4 with CSS-first configuration (main.tw.css):

@import "tailwindcss";

@theme {
    --font-primary: 'FigGrotesk', sans-serif;
    --font-paragraph: 'Forma DJR Text', sans-serif;
    --default-font-family: var(--font-paragraph);
    /* ... other theme variables ... */
}

The "Forma DJR Text" font is configured both in the Tailwind theme and the Nuxt fonts config.
