/* ===================== Ospi left panel: System pill (§A) =====================
   Approved redesign. One 46px pill over three pre-rendered panels. The pill is
   a native x-scroll-snap strip with edge pads, so it ALWAYS overflows and the
   pager's [data-hscroll] guard pins the page for a gesture that starts on it.
   No bundler, tokens only, no hardcoded colours. The frost is two pseudo-panes
   (blur-advice.md §3) with a clear window at 50% ± 64px; the ring is 1.5px
   --accent, no ticks, no fill (blur-advice.md §5). The ring's own state class is
   namespaced (.ospi-ring-pulse): a bare `.pulse` is a global 8px live-dot utility
   in style.css, and it applied to the ring the first time it pulsed. */
/* Bottom-dock clearance (owner, this round x2): the pill docked at the page's
   bottom sat on the iOS home indicator in the INSTALLED app. The dock reserves
   max(home indicator, 12px) + 16px breathing room under the pill, and the
   installed shell grows the page box below the visual viewport by the measured
   --sb-fill (style.css html.pwa { height: calc(100dvh + var(--sb-fill)) }),
   which env()/safe-area-inset-bottom does NOT cover — so the same --sb-fill is
   added again. That pins the pill's bottom edge >= 24px above the VISUAL
   viewport bottom on a real installed iPhone (28px with no inset, 50px with a
   34px inset, 28px on the installed shell whose box grew by 34px).
   env() is read directly on purpose — NOT --capsule-clearance, which folds in
   --sb and the old 88px capsule gutter. --test-safe-bottom / --sb-fill are the
   harness hooks tokens.css and style.css already use, so headless geometry can
   simulate a home indicator and the installed shell. */
