   S HARI GLOBAL — POLISH LAYER  (17 Oct 2026, owner's "ultra-polish" prompt)

   Loads LAST (after depth.css). A surgical top-up on the premium3d / hyperos /
   liquid work that is already live — four small, verified weak spots, nothing
   rebuilt:

     1. the hero route-band coach marker read as a tiny indistinct shape
        -> larger and sharper so it reads as a bus
     2. the phone's feature-icon strip scrolled but cut off flat on the right
        with no hint there was more -> a soft right-edge fade
     3. tactile press feedback was on the bespoke keys (sb-pay, nav-cta, hh-act,
        bottom-nav) but not on the ordinary .btn -> a gentle, consistent press
     4. the ticket PNR pill simply appeared -> a one-time cinematic light sweep
        when the ticket is ready (sb-tk-imgw gains .ok)

   Rules, same as the layers below it: colour / light / shadow / transform /
   opacity only — no id, hook, label, control or logic change. Every bit of
   motion stops for prefers-reduced-motion, html[data-motion="reduced"] and
   html[data-tier="low"]. Built on the existing --p3-* tokens so it follows the
   palette picker and light / dark / AMOLED automatically.

   1. HERO ROUTE-BAND COACH — bigger, sharper, reads as a bus
   The marker is a flat webp driven along .p3-line by premium3d.css's p3Drive
   (transform: translateX). We only touch its box, its artwork size and its
   contrast / shadow — never its transform — so the drive is untouched.
   ===================================================================== */

  height:40px;margin-top:-20px;background-size:80px 40px;
  filter:contrast(1.08) saturate(1.06) drop-shadow(0 7px 7px rgba(0,0,0,.6)) drop-shadow(0 1px 1px rgba(0,0,0,.4));
}
/* the dotted road and the orange fill a touch stronger so the band reads at a glance */

   2. PHONE FEATURE STRIP — a soft right-edge fade that says "scroll for more"
   .p3-feats is a nowrap, overflow-x:auto row below 860px. The mask only fades
   pixels; it never changes the layout or the scroll.

   3. CONSISTENT TACTILE PRESS on the ordinary .btn
   The premium keys keep their own, richer :active (higher specificity wins):
   sb-pay, nav-cta, hh-act, bottom-nav. This only reaches the plain buttons
   that had no press at all.
   ===================================================================== */

   transitions the base .btn already animates — the shorthand replaces, so the
   common properties are listed back in. */

   4. TICKET PNR — a one-time light sweep + a gentle pop when the ticket lands
   premium3d.css already styles .sb-tk-pnr as a pill; it gets a reveal the
   moment its wrapper flips to .ok (the real engine state, not a timer).

   5. HYPER-BUS COACH WHEELS — make the real rim spin read clearly
   (18 Oct 2026, owner: the top coach's wheels don't look like they turn,
   make them turn clearly like the coaches lower down.)
   The rims already rotate (hyperos.css .shg-wheel-spin / shgAlloySpin) — the
   motion is just too quiet on the small chrome hub. This keeps the real photo
   wheel (no drawn spokes) and only: shows more of the alloy (less edge fade),
   lifts the alloy's contrast so the bolts read, and spins a touch faster.
   Nothing overrides hyperos's motion gating — the duration here has no
   !important, so the reduced-motion / data-motion rules there still win.

   6. HERO COACH WHEELS (#hero3d) — same real-photo rims as #hyperBus
   (19 Oct 2026, owner: of the three coaches only the first one's wheels
   stood still.) #h3Bus was a bare photo. It now sits in .p3-coach, which
   carries the .p3-bus class (size, parallax, float, shadow, motion gating
   all unchanged), so the two rim hubs float WITH the coach. Same file, same
   rim measurements as hyperos.css §7, so the percentages are identical.
