/* ── Auto scheme: adapts to any background colour ──────────── *
 *
 *  How it works:
 *
 *  1. Neutral gray tint (rgba ~128,128,128) — neither pushes
 *     the glass bright nor dark, so it reads on both.
 *
 *  2. Higher blur + brightness boost — further averages the
 *     sampled area toward a mid-tone and lifts very dark bgs.
 *
 *  3. Dual border — a white outer stroke stays visible on dark;
 *     the inner dark box-shadow stays visible on light.
 *
 *  4. Text shadow halo — white text with a soft dark shadow
 *     punches through a light background without looking heavy
 *     on a dark one.
