/*
  Vantage design system.

  Palette + shapes are lifted from the FieldCore admin UI (Tailwind slate scale +
  the violet "partner" accent #7c3aed) so the internal console feels like part of
  the product: light theme, 13px base, rounded-xl cards, uppercase micro-labels.

  Sections:
    1. tokens          2. reset/base       3. login screen
    4. app shell       5. nav              6. cards & stats
    7. tables          8. buttons & tags   9. kanban + inbox
   10. drawer         11. tree            12. utilities
