   TECHSPACR — PORTFOLIO STYLES (v4)
   Generic bento-style cards (icon box + title + description + tags),
   NOT the big device-mockup "case study" card layout. The icon box
   itself carries the interaction: loads tilted ~7deg, straightens on
   click with a spring ease, hint fades out, and the "View Case Study"
   button fades in about 0.3s later. Same box/animation whether it
   holds a real screenshot or the abstract per-category fallback.
   Relies on tokens/fonts already defined in style.css — load that
   first, then this file.
