   FLIGHT — aurora module.
   The canvas (#fx-aurora) is fully positioned + layered by base.css
   (position:fixed, inset:0, z-index:var(--z-aurora), pointer-events:none).
   All painting happens in js/aurora.js. This file only adds cheap, safe
   reinforcements so the backdrop never interferes with foreground reading.
   ============================================================================ */
