   TOOLSHUB4U — SEO TOOLKIT DESIGN SYSTEM
   Shared component library for every SEO tool page.
   Uses main.css tokens (--surface, --border, --accent, ...) so
   light and dark themes both work automatically.

   Components:
     .tk-section / .tk-shell / .tk-header / .tk-grid / .tk-card
     .tk-field / .tk-label / .tk-input / .tk-select / .tk-textarea
     .tk-row / .tk-btn / .tk-tabs / .tk-stats / .tk-stat
     .tk-score / .tk-badge / .tk-issue / .tk-table / .tk-progress
