/* =====================================================================================
   sellers.css — the Sellers / Potential Vendors page (templates/index.html at /sellers) and the
   Seller Details + Seller Communication modals on the Heritage design system (m4s.css tokens).

   Scopes:
     .sellers-page        page body rendered by templates/index.html + static/js/dashboard.js and
                          static/js/modules/sellers/{sellers-table,vendor-conversion}.js
     #sellerDetailsModal  body rendered by static/js/modules/sellers/seller-details.js (sdm-*)
     #communicationModal  body rendered by static/js/modules/modals/communication-modal.js (cm-*)
     #confirmModal        markup in templates/_shared_modals.html (was an inline <style> there)

   Linked from index.html's head_extra and from templates/_shared_modals.html (next to
   item-details.css) so /orders and /review get the modal rules too. Every page is on base.html,
   so the m4s.css tokens (--ink, --muted, --line, --tile, --serif …) are always defined; the few
   concrete colours below are the Heritage palette (forest #336659, navy #0E1C4F).
   State-driven colours come from classes/attributes the JS maintains (sort-asc/desc, .tag.ok,
   --st on the status pill, data-kind on messages), never from inline style="" in the renderers.
