/*
 * Ambient gradient ground (--tl-bg-gradient, tokens.css) — a dedicated,
 * inert full-viewport layer instead of `background-attachment: fixed` on
 * body. `background-attachment: fixed` cannot be promoted to its own GPU
 * compositor layer in most engines, so it repaints the full viewport on
 * every scroll frame — and .site-header's `backdrop-filter: blur(20px)`
 * sits directly on top of it, so that blur could never be cached either
 * (its source was being invalidated every frame it sampled from). A plain
 * `position: fixed` element is a real, stable compositor layer: it never
 * moves relative to the viewport, so the browser paints it once and reuses
 * it, and the header's blur now reads from a source that actually holds
 * still. This also fixes iOS Safari, which has never properly supported
 * `background-attachment: fixed` (it used to detach and scroll with the
 * page there instead of staying put).
 *
 * z-index: -1 relies on body/html having no other negative-z-index sibling
 * to fight with — true here, nothing else in this codebase uses one.
 * aria-hidden + no interactive content, so nothing here affects the
 * accessibility tree.
