   De Bote 047, Something Wicked 049). Each card is a <figure class="media cs-card"> filled by
   js/cards.js: the case study frame (white, gloss, square corners) with
   tape, the card inside it and, on a moving card, its pause button. A
   project sets the card's colours (--bg, --fg) and its own parts; sizes are
   in cqw of the card. Small text is never faded (opacity), so it keeps
   4.5:1.
