/* /portfolio 案例成果 (pages/portfolio, 2026-10-14). Needs rt-hue.css (tokens, .hx-head, .hx-win, .hxa-band/.hxa-grid art).
   1. hero: three tilted columns of real client screenshots drift up / down behind the copy (CSS only; pg-portfolio.js
      pauses them off screen and with the small corner pause button)
   2. featured cases (博山, 元智): screenshot in a browser window + the animated case art from rt-hue
   3. coloured category tiles + work cards (hover: lift, glow in the category hue, the screenshot scrolls down)
   4. folded member / multimedia blocks, service paths, preview + video modals (moved to <body> by the JS)
   Both themes follow the site toggle; light overrides at the end. */
