/*
 * NTT refine layer (Oct 2026). Loaded last, on every page.
 *
 * What it does, and why:
 * - Apple-grade materials: SF Pro on Apple devices (Inter elsewhere), the
 *   #f5f5f7 canvas, a frosted top bar, Apple's action blue, continuous-feel
 *   radii. Depth from one hairline, never border + shadow together.
 * - One gradient with a job: a soft aurora behind the top of each page in
 *   NEXORA's own lime and teal, fading out before content starts. No purple,
 *   no gradient text, no glow.
 * - Unslop pass: labels in sentence case without tracking (no shouty
 *   eyebrows), one primary button per view, motion only as one settle on
 *   arrival and on press, all of it off under reduced motion.
