/*
 * Warm pointer-tracked "sun" behind each section title. Kept very soft so
 * it reads as atmosphere, not as a light source.
 *
 * Important constraints, earned the hard way:
 *   - NO `filter: blur()`: Safari rasterizes filter primitives to the
 *     element bounding box, and any near-transparent pixels at the box
 *     edges become a faint rectangle visible against the dark backdrop.
 *     Instead, softness comes from the gradient's own color stops fading
 *     gracefully well inside the element's box.
 *   - The JS in app.js clamps the pointer parallax to a narrow band
 *     around center (~45–55% / ~45–52%). Prior versions mapped the whole
 *     viewport to 0–100%: when the cursor approached the right edge, the
 *     ellipse center slid to ~90% of the box and its bright half was
 *     clipped against the element edge, rendering as a hard horizontal
 *     gold streak. Clamping means the glow breathes gently without ever
 *     reaching an edge.
