/* ==========================================================================
   RESEARCH LABS — cinematic project cards for labs.php
   Same shell language as product-showcase.css (tilt-card, pulse-dot,
   status-color variants) but tuned for research-stage framing instead of
   live/dev/soon, and built around a generative SVG visual per project
   rather than the architecture-diagram + metrics combo used for shipping
   products.
