/* =========================================================
   MSC ACTION BUTTONS
   File: msc_action_buttons.css
   Depends on: msc_core_tokens.css + vertical token file
   Purpose: Token-driven buttons for course, lesson, dashboard and simulation actions.
   Rule: primary/secondary inherit vertical identity; status buttons use global status tokens.
