/* =============================================================================
   Professional desk — vanilla research views
   -----------------------------------------------------------------------------
   Session / Positioning / Decision already speak the desk language in React.
   Everything else in the Professional rail is still a Flask view. This sheet
   applies the language.md checklist to those views in one place:

     no in-page title or lecture lead
     headline numbers → Metric boxes
     chapters → Section (16/600 + hairline), not raised cards
     lists → table-like rows
     view switches → Segment
     empty → one quiet sentence
     ? circles and kpi "i" pips gone
     full well, --mds-gutter, no centred max-width

   Scope: Professional audience + React shell guest (unported route).
   Journal / Sizing / Playbooks / TradeAI already have their own desk pass.
   Do not restyle past this unless a page is critically broken.
