+All five animated backgrounds were rewritten for smoother, more organic motion. Each background drives its own single drift/scroll keyframe (no secondary glow or blink layers):
 
-- **Digital Rain** — added a phosphor glow flicker (`animRainGlowKeyframe`, 2.1 s) layered on top of the column scroll; stripe opacity increased for better visibility
+- **Digital Rain** — column scroll keyframe; stripe opacity increased for better visibility
 - **Star Drift** — each of the three dot layers now moves by exactly its own tile width/height per cycle (`−130 px`, `−190 px`, `−260 px`), eliminating the visible seam on loop
-- **Grid Pulse** — independent brightness oscillation (`animGridBrightnessKeyframe`, 3.3 s) runs alongside the size breathe (4 s) at a prime period ratio so they never synchronise
+- **Grid Pulse** — size breathe keyframe (4 s)
 - **Aurora Flow** — four gradient layers now have individual `backgroundSize` values (`200%`, `250%`, `300%`, `220%`); the keyframe drives each layer through a distinct 5-stop path, replacing the robotic single back-and-forth
-- **Fireflies** — glow pulse (`animFirefliesGlowKeyframe`, 2.3 s `filter: brightness`) and opacity blink (`animFirefliesBlinkKeyframe`, 1.7 s) added on top of the position drift; prime periods create unsynchronised bioluminescence
+- **Fireflies** — position drift keyframe with per-firefly duration/delay so motion stays unsynchronised
