 * Fizzbrook Kombucha — a one-page project in live 3D (tickets/SC-03.md, SC-04.md).
 *
 * Layers of the pinned stage, back to front:
 *   .field     z0  the field of a colour, lit like a cyclorama
 *   .word …    z1  what is painted on a field: the monument word, the sun, the phrase, the brook
 *   #gl        z2  the cans: a transparent canvas, so the fields show around them
 *   .marks     z3  two crosses and a tag
 *   .bar …     z4  the interface, which stands still: the captions of act 1, the callouts
 *                  of act 2, the line and the button of act 4
 * After the stage, in the flow of the page: .foot.
