/*
 * The star chart sits directly on the page's starfield background with no
 * frame — it reads as a gravitational-lens "portal" into the same star
 * field (event-horizon style: glowing rim + warped halo).
 * - The canvas stays sharp through most of its radius, then a warped
 *   "lens" ring (SVG turbulence + displacement, see #portal-lens) refracts
 *   its outer ~30% just inside the rim, like looking through curved glass.
 * - A second, stronger-warped ring (#portal-lens-outer) bleeds past the
 *   circle's edge, swirling the starfield around the rim.
 * - A glowing tan rim (box-shadow) traces the photon-ring edge, and a
 *   raking drop shadow grounds the disc against the background.
