/* Soft brand-blue glow. Built as a giant circle *concentric with the arc*
   (same center, radius = arc's radius + R) — this is necessary because the
   arc's curve genuinely dips a lot across the viewport width (hundreds of
   pixels, since it's a huge circle), so anything shaped as a flat/fixed-
   height box would poke out past the arc's own curve near the edges. A
   flat-bottomed dome was tried and rejected for exactly this reason.
   R is generous (200px/160px) so the radial-gradient (fixed-pixel sized,
   positioned to line up with the arc's own peak) can fully fade to
   transparent with real margin left before the outer's hard circular
   clip — giving the blur genuine room to soften the top edge instead of
   being cut short. Two layers:
   - .hero__glow (outer): position/size/animation + circular overflow clip
     + horizontal fade mask, matched to the arc's own mask stops so the
     glow visually spans the full width of the visible curve, edge to edge.
   - .hero__glow__inner: the actual radial-gradient + filter:blur. */
