feat: set Poppins and Inconsolata as default fonts

[tomusdrw]

Summary

• Configure Poppins as the default sans-serif font and Inconsolata as the monospace font via Tailwind v4 @theme tokens (--font-sans, --font-mono)
• Add Google Fonts loading for Storybook via preview-head.html
• Clean up unused --font-display CSS variable and broken Oswald @font-face
• Document font usage and override instructions in theme.css and README.md

Test plan

• Verify Storybook renders components in Poppins font
• Verify font-mono utility uses Inconsolata
• Verify the built dist/style.css contains --font-sans and --font-mono tokens
• Verify a consuming project can override fonts via its own @theme block
