/* aarti.css — circle the thali around Bappa.
 *
 * The stage is a square; the murti portrait is a circular crop of the darshan still.
 * js/aarti.js owns the thali's transform (it rides a circle of radius --r) and paints
 * the light trail into a canvas the same size as the stage — the additive blend
 * happens inside the canvas (globalCompositeOperation), never as a CSS blend mode.
