/*
 * Ovenholt, «One pizza at a time» — 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).
 *
 * 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 name of the pizza on the orange of the fire, its four
 * words and four round stills on the yellow.
 *
 * 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).
 *                 The oven is seen through its own mouth — an arch that stands on the foot
 *                 of the yellow page and opens to the whole screen (clip-path, set by the script)
 *     .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. 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 pizza box on the charred table.
 *
 * The words take their ink from what lies under them (data-tone): the flour's cream on
 * the dark room and the fire, the dark of the room on marble, on the orange and on the yellow.
 *
 * Brand colours (tickets/SC-25.md): room #1c1410, ember #e4572e, yolk #f4d35e.
