/* ==========================================================================
   Stock publication system — shared primitives for the stock pages that sit
   beside Research (Báo cáo tài chính, Nhận định, Tài liệu nghiên cứu).

   Values are copied from the approved Research page (premium_article.css) and
   the Overview v2 page (stock_overview_v2.css): paper / ink palette, Newsreader
   + Inter, hairlines instead of boxes, the Research stock navigation. Research
   itself is NOT edited or made to depend on this file; if the two ever need to
   be one system, consolidate deliberately in a later pass.

   Namespace: .stp-*   (page-specific rules live in their own stylesheet)
