/* ============================================================
   CREDITS  (core/credits.js)

   Lutfi's "Quantum Dawn Portrait Credits" design, as a look for the hub's
   "credits" sheet. The design's sizes are kept for a laptop; its own 720 /
   400 px layouts for phones held upright; a phone held sideways gets a
   compact window (the big title shrinks to one line, smaller portraits)
   so the team shows without scrolling past the heading first.

   Every rule starts .sheet-credits .qcr, so the hub's older .qd-credits
   rules (hub.css, the plain fallback sheet) and these never meet.
