/* Iter 10.23 — Mobile horizontal-scroll fix WITHOUT breaking sticky header.
   IMPORTANT: putting `overflow-x: clip|hidden` on <html> or <body> creates
   a new sticky containing-block boundary on some browsers (notably iOS
   Safari), which silently breaks `position: sticky` for the top site
   header. So we MUST keep both <html> and <body> at `overflow: visible`.
   To still prevent horizontal scroll caused by stray overflowing children
   we instead:
     1) Fix the actual overflow at the source (see Iter 10.22 header-actions).
     2) Lock the body to `width: 100%; max-width: 100vw` so the layout
        cannot grow wider than the viewport.
     3) Apply `overflow-x: clip` to <main> (.page-main) so any future
        widget that overflows still gets clipped at the content level —
        without touching the sticky containing block (which is the
        viewport / html). */

   Angle mapping (semicircle, 180° spread from -90° to +90°):
     -90° = 0ms (far left, green tip)

     +45°   = 10ms
     +67.5° = 30ms
     +90°   = 100ms (far right, red tip)
   We make the needle randomly wobble across 0.4–3.1ms (green→yellow zone),
   occasionally dipping toward 0.4 and once briefly to 3.0 to feel "alive".
