/**
 * Research Arsenal — refinements beyond theme.json. v1.1
 *
 * Design language: laboratory-packaging minimalism. Paper white, ink
 * black, one emerald. Hairlines carry structure; the black-and-white
 * thermal label is the signature voice. Motion is quiet and earns its
 * place.
 *
 * Sections:
 *   1. Tokens & base
 *   2. Motion, reveals & focus
 *   3. Header
 *   4. Signature elements (mono labels, rules, doc strip, thermal label)
 *   5. Block styles (ghost / text-arrow / spec list / framed group)
 *   6. Product cards & shop grid
 *   7. Single product — batch documentation layout
 *   8. Cart, checkout, notices
 *   9. My Account
 *  10. Forms & inputs
 *  11. Footer
 *  12. Responsive
