/* ============================================================
   Palantir-capabilities — case-study "proof" slide components.
   Carried over from the general capabilities deck (its FinOps,
   FactoryOS and PetitionVerify slides have a denser, image-led
   layout than the original palantir case studies). styles.css
   already provides .cs-layout / .cs-metrics / .metric; this file
   adds only what those slides need on top:
     - the .slide.proof compaction + spacing fixes
     - the demo video + image frames
     - the two overlapped-image stacks (mockups, screenshots)
   Kept in a separate file so the carry-over is easy to review and
   doesn't touch the shared styles.css (which the export/print
   HTML also loads).
