/* ── iOS Safari compositing fix ─────────────────────────────────────────────
Shibuya's .sy-head-blur uses -webkit-backdrop-filter: blur(12px), which
creates a GPU compositing layer. On iOS Safari this disrupts rendering of
two distinct things in sibling/adjacent sticky elements:

1. -webkit-background-clip: text → gradient text goes invisible
Fix: isolation: isolate on .sy-head-brand (creates its own stacking
context, shielding the gradient-clip composite from the blur layer).

2. Plain text rendering in .sy-breadcrumbs → link text goes invisible
while CSS-mask icons in the same bar remain visible (icons use
background-color + mask, a different GPU path than text).
Fix: transform: translateZ(0) on .sy-breadcrumbs-inner forces it into
its own compositing layer so text renders independently of the header.
