/*
 * Mossling Matcha Bar — a one-page project in live 3D (tickets/SC-12.md).
 *
 * Layers of the pinned stage, back to front:
 *   .field     z0  a flat field of moss with the word on it: only what a page without
 *                  the script (or without WebGL) shows
 *   #gl        z2  the room and the set, drawn by the script: the stone counter, the
 *                  painted wall with the word, the light through the leaves, the things
 *   .shade     z3  shade along the top of the frame, under the bar
 *   .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.
 *
 * Brand colours (tickets/SC-12.md): matcha, moss, a green for each powder. The wall of
 * the room takes four greens in turn — moss, matcha (the Ceremonial green), the Daily
 * green, the Culinary green; cream is the colour of the bowl and of type, never of a field.
