/* =========================================================================
   Marketplace platform stylesheet — hand-authored.
   No Tailwind / Bootstrap / Sass build. CSS custom properties + logical
   properties so a single sheet serves LTR and RTL.

   Layers:
   1. Tokens          (colors, type, spacing, radii, shadows, motion)
   2. Reset           (base elements)
   3. Layout          (panel shell, grid, container)
   4. Components      (buttons, inputs, cards, tables↔cards, modals, toasts, …)
   5. Utilities       (a small set; no proliferation)
   6. RTL adjustments (only direction-flipping icons; layout uses logical props)
