/*
 * Kettlewren, «from leaf to cup» — 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-22.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: how a tea is brewed, the phrase of the house.
 *
 * 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 the second act it is a round window (clip-path, set by the script) —
 *                 the window of the tea house — that opens on the shelf
 *     .leaders    the lines from a tag to its thing
 *   .cue        the tags 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 large
 *               figures on the green of the dry leaf, «Six ways.» on the night
 *   .bar        the name and the stations of the leaf, paper labels fixed over all of it
 * After the film, in the flow of the page: .foot — the card from the tin.
 *
 * Brand colours (tickets/SC-22.md): night #12211b, tea gold #c9a227, paper #e8e2d0.
