/* ============================================
   DND Short Factory — Case Study (Light)
   Extends dnd-pipeline.css. Flips the dark gaming
   theme to the site-wide cream/rust editorial
   palette. Mirrors the approach used by
   dnd-knowledge-graph.css.

   Deliberate dark contrast moments are preserved:
   - .raw-transcript  (terminal-style transcript)
   - .data-block      (JSON before/after)
   - .waveform-container (audio waveform)
   - .code-block      (terminal output)
