/* ==========================================================================
   Alto Field Tools — main.css
   Catalog Search Workbench shell (DEC-018, docs/fable-ui-brief.md)
   Original Alto Well & Pump branding. Pattern inspired by faceted-search
   UX; no third-party code, chrome, or assets copied.

   Sections:
     1. Tokens
     2. Base / reset
     3. Top bar + menu bar
     4. Login
     5. Scoped search row
     6. Catalog workbench layout (two-column + rail)
     7. Result cards
     8. Detail pages (item / assembly)
     9. Imports & summary (carried over, unchanged behavior)
    10. Responsive: tablet (>=640px) and desktop (>=960px)
