   Atmospheric layer — five large soft-blurred blobs in mid/deep brand

   (140px) + low opacity (0.20–0.32) keeps them as ATMOSPHERE, not
   distinct shapes. Bright blue held back to 0.20 so the frosted
   header never reads aqua.

   Mix-blend-mode: soft-light keeps blobs visible on dark sections
   (charcoal, navy) AND on light sections, without overpowering either.

/* ============================================
   AMBIENT BACKGROUND — galaxy-wisp pixel field
   ============================================
   Two fixed-position layers that paint a fine pixel-grid "wispy" field
   along the left and right edges of the viewport, fading to a clean
   white center. Rendered via SVG inside each layer; procedurally
   generated in the component so nothing is bundled as a static asset.

   Positioning: position: fixed, so it covers the viewport regardless of
   where the component is dropped in the page. pointer-events: none, so
   clicks always fall through to actual content. Masked with a linear
   gradient per side to dissolve into the center.

   Final settings (approved 2026-04-21):
   - Motion: drift on, two different durations + phase offset per side
   - Density: Sparse  (densityMultiplier = 0.90)
   - Opacity: Whisper (opacityCap = 0.14)
   - Glitch:  High    (tickMs 80, perTick 3)

     The blend mode does the heavy lifting:
       - white  × low-opacity blue  ≈ white  → dots invisible on white
       - dark navy × low-opacity blue ≈ deeper navy → dots visible
       - light card × low-opacity blue ≈ very faint tint → barely visible
     Result: noise pixels show on colored section backgrounds (where we
     want them) and disappear over white content (where we don't).
