/* ==========================================================================
   Portfolio frame — shared by every case study.
   The frame owns navigation, case opening, section headings, body type,
   captions, cards, stages and the footer. Each case only sets:
     --accent  the case's signature colour (nav progress, emphasis)
     --hl      highlight used for the underline sweep and primary buttons
   Everything inside a .pf-stage (mockups, game screens) belongs to the case.
