- Move @import "@maizzle/tailwindcss" + @theme tokens to packages/email/email.css
- Layout uses <link rel="stylesheet" href="{{ cssPath }}" inline> — Maizzle's
  expandLinkTag reads the absolute path and expands it to a <style> tag, which
  the second compileCss pass then processes with @tailwindcss/postcss + LightningCSS
- render.ts passes cssPath as a local so the expression resolves inside the layout
- Layout head is now clean HTML with no inline style logic
