/*
 * Aurevane, «One scent» — a page played from footage, and a page that travels
 * (tickets/SC-48.md; the footage, the words, the faces and the colours are those of
 * ../prototype-film, tickets/SC-33.md).
 *
 * This sheet is written in two halves.
 *
 * First, the page as it is without the script, or where motion is not wanted: every shot
 * is a screen of its own — its still, its words at the foot of it — and between the acts
 * lie the blocks of the page: three stills of the footage, the name.
 *
 * Then (html.live, set before the first paint when the film will play) the page becomes
 * four acts with real scroll between them:
 *   .act        as tall as its scene is pinned for, plus one screen (--pin, set by the script)
 *   .stage      the scene of the act: a sticky screen. The page brings it in from below,
 *               holds it and carries it away upwards
 *     .frame      the picture: the first frame of the act (.poster) until the film is
 *                 there, then the footage (.screen, a canvas of its own in every act).
 *                 In two acts it is a window (clip-path, set by the script): an arch —
 *                 a doorway — that opens to the whole bench, a card that opens to the table
 *     .leaders    the line from a word to its thing on the bench
 *   .cue        the words of an act lie on the page, not on the scene: they come from
 *               below and leave upwards with the scroll while the picture stands pinned
 *   .block      what lies between two acts and scrolls as any page does: three stills on
 *               the gold, the name on the mist
 *   .bar        the name, fixed over all of it; .steps — the marks of the steps, in the
 *               lower left corner
 * After the film, in the flow of the page: .foot — the lid of the box.
 *
 * The words take their ink from what lies under them (data-tone): cream on the dark of
 * the atelier ("night"), the night's ink on the white, on the gold and on the linen ("day").
 *
 * Brand colours (tickets/SC-33.md): night #0d0d12, gold #d9b26f, cream #f2e9e4.
