  /* Hero: immersive, landscape whole-venue scenes.
     2026-09-23 real-window fix (A12227, revised after review A12231).
     A real browser window is shorter than the screen (tabs + address bar):
     1920x960, 1536x730, 1366x650 give a hero 2.2-2.4 times as wide as it is
     tall, but the scenes are 16:10 and their installations span up to two
     thirds of the picture height. Full-bleed cover there must cut an
     installation or put the copy on one. So:
     1. Up to 1.88:1 the scene stays full-bleed. Wider than that, the hero
        becomes an editorial split: a brand-ink side rail on the left with a
        hard edge, the scene frame on the right. The rail is never a sliver:
        it is at least max(160px, 11vw) and grows with the extra width
        (100cqw - 1.88 x height). The frame is then never wider than 1.88:1
        and never narrower than 1.6:1, so the picture always covers it
        edge to edge and nothing is cropped left or right.
     2. The rail carries the scene number, a short brand-yellow rule and the
        scene name at the top (built per slide in home.html, fades with it)
        with the pause control under them, and the carousel dots at the
        bottom; the headline starts in it. (A pause pill next to the dots
        would not fit a 160px rail and would straddle the hard edge.)
     3. Each scene carries its own anchor --t (share of the picture height
        kept above the frame top, per scene in build_qixiang_site_v5.py
        HERO_DESKTOP); the offset is clamped so the picture always covers the
        frame. Container units make this exact at any window size; a browser
        without them falls back to --pos-d, full-bleed and no rail.
     4. The copy scales with the width up to 16:9 and with the height beyond
        (--hu), so on short windows it stays a low band under the
        installations; the headline is held to 3.4vw so on 16:10 windows it
        ends before the swing on the right. */
