/**
 * HyperKit Photo Fan.
 *
 * Every photo is absolutely positioned in the middle of the stage and moved
 * out from there. PHP hands each one two numbers — a centred index in
 * --hk-pf-i and the same value normalised to -1…1 in --hk-pf-t — and the
 * single transform below turns them into the spread, the arc and the tilt.
 *
 * The stage keeps its own height and width so the page does not reflow when
 * the fan opens; only transforms animate, never layout.
