/* ============================================================
   MOLVERN LABS — Work / case studies
   Shared by /work (the index) and each case study page.

   Built on the semantic theme tokens: --color-navy* are the
   backgrounds and --color-white is the text colour, and they swap
   in light mode, so nothing here hard-codes a surface colour.
   The only fixed colour is the project accent (--cs-accent),
   sampled from the client's own interface.
