/*
 * Umberly, «Bar by bar» — a page played from footage, and a page that travels
 * (tickets/SC-48.md; the footage, the words and the colours are those of ../prototype-film, SC-29).
 *
 * 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: the maker's line on the gold, the strip of four stills.
 *
 * 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 act 2 it is a tall column beside the word «Cacao,», in act 4 a window
 *                 in the umber (clip-path, set by the script): both open to the whole screen
 *     .leaders    the line from a word to its thing
 *   .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: the line on
 *               the brown and on the gold, the strip of stills on the umber. A block that
 *               follows a flood lies over the end of the act before it, so its words
 *               rise on the colour while that still stands pinned
 *   .bar        the name and the steps of the story, fixed over all of it
 * After the film, in the flow of the page: .foot — the foil and the paper band, opened.
 *
 * The words take their ink from what lies under them (data-tone): cream on the dark of
 * the workshop and the walnut ("night"), umber on the white marble and on gold ("day").
 *
 * Brand colours (tickets/SC-29.md): umber #1a0f0a, brown #7b3f00, gold #d4af37.
