/* Surfwise "Open in Surfwise" page (/check/ + the demo link page): the page's own layer (2026-10-16).
   Loaded AFTER assets/site.css and only adds to it; every rule is scoped to body.op-fx, so the home
   page and the old .op-page rules of site.css never change. What this file adds:
   1. the home's look on this page: the sticky header, the dotted hero field, the painted CSS aurora blobs
      of site.css (the WebGL aurora canvas is gone, 2026-10-16m), the dark "night" panel for the how-to block;
   2. the home's photo-real iPhone 16 Pro (assets/iphone.css: ONE pre-rendered frame image over the
      screenshot, no 3D plates) showing the four real app screens in a loop (opacity only) with a scan
      beam, a step chip and four dots (PC only: the phone is never shown on a phone, where the page stays
      compact); its slot gets a still base angle here and ONE inline transform from check.js (pointer
      tilt, fine pointers); the same component is the phone of the how-to guide;
   3. the futuristic touches: HUD corner brackets round the paste box and the link card, a scan beam
      across the destination row, a light running round the main button, a halo + pings behind the
      app icon, a glowing cursor ring (fine pointers only);
   4. once-only reveals: the heading's words rise and fade in with a small stagger, cards rise once.
      NO text scramble / decode anywhere (owner 2026-10-16). Hidden-until-revealed styles exist only
      under html.js:not(.rv-all); the head script adds .rv-all when check.js has not started after
      2.5 s, check.js adds it on reduced motion, without IntersectionObserver or on any error.
   PERFORMANCE contract (same as site.css / future.css): animated properties are transform / opacity
   (+ the translate / scale properties) only; no backdrop-filter, no filter, no animated box-shadow,
   size or position; no preserve-3d, no custom property written per frame (2026-10-16m: the --px/--py/--sy
   tilt on #op-show, the 4-plate phone, the WebGL canvas and 8 pulsing bracket pseudo layers lagged); every infinite animation is paused unless its block is on screen (.is-in from
   check.js) and while the tab is hidden (html.pg-off); pointer effects only on (hover:hover) and
   (pointer:fine); the whole motion layer is off under prefers-reduced-motion. */

/* =============================== 9. SHADOWS AS IMAGES (2026-10-17) ===============================
   As on the home (assets/future.css, section 5): the big blurred box-shadows are the same shadows rendered once with
   Chrome (assets/img/sh/*.webp) and drawn as a 9-slice border-image on a pseudo element in the shadow's place. The
   paste box and the link card draw their own; the how-to panel clips its overflow, so its shadow sits on the .vid-sh
   wrapper (which also carries the panel's reveal, so the shadow slides in with it as before). */
