/* Ambient margin decoration on wide viewports — vertical CRT scan-line band
   running parallel to the 64ch reading column on both sides. The reading
   column width is NOT changed; the decoration lives in the absolute side
   space outside the column. Activates above 1024px where empty side space
   starts to feel like a visual void on the dark theme. Mobile/tablet stay
   unchanged.

   Layered background:
     1. A vertical scan-line SVG data-URI — fine 1px phosphor verticals every
        4px, the "CRT phosphor mask" reference.
     2. A horizontal beam-line dash pattern overlaid at 70% opacity, the
        "horizontal scan-line" reference that the .crt-overlay uses globally.
     3. A pair of phosphor edge-rules at the band's inner and outer borders
        so the band reads as an editorial side-margin rule, not as noise.

   The band has a soft top/bottom fade (mask-image) so it doesn't compete
   with the article header or footer.
