-  Grain Overlay — animated film grain texture.
-
-  Usage: paste this snippet into your composition's HTML.
-  The overlay covers the full viewport with pointer-events: none
-  so it sits on top of all content without blocking interaction.
-
-  Customize:
-  - opacity: adjust .grain-texture opacity (default 0.15)
-  - speed: change animation duration (default 0.5s)
-  - texture: swap the background URL for a different pattern
-  - z-index: adjust #grain-overlay z-index to layer correctly
