/*
 * Squeeze headline: a poster for a six-night track race. Three lines, each set at its own size so
 * all three end on the same right edge (the sizes are measured for Anybody at wdth 115, wght 800;
 * relative to TURNS, LEFT is 1.529 and ONLY. is 1.25). Change the words and you re-measure.
 *
 * Order (one --stagger step is 80ms):
 *   0 to 1.6s    each line squeezes in from 150% width, letter by letter, on a spring.
 *                LEFT and ONLY. close from the right; TURNS closes from the left, like riders
 *                swapping on the banking
 *   0.2 to 1.8s  the track outline draws behind
 *   1.0 to 1.9s  the three lane lines (measure, sprinter, stayer) run out under the headline
 *   1.2 to 2.1s  date, venue, copy and buttons rise in
 *   after        scene.js swells the letters nearest the pointer (width and weight), while the
 *                rest of the line gives way, so each line keeps its length
