<!--
Vignette — cinematic radial darkening overlay.
Usage: paste this snippet inside your composition's positioned stage.
The overlay covers the full viewport with pointer-events: none so it
sits on top of all content without blocking interaction.
Customize:
- --vignette-color: edge color and alpha (default rgba(0, 0, 0, 0.7))
- --vignette-size: where the transparent center ends (default 45%)
- --vignette-edge: where the color reaches its final stop (default 100%)
- --vignette-shape: ellipse | circle (default ellipse)
- z-index: defaults to 90 so grain-overlay (100) reads on top

Timeline integration example (add to your composition's GSAP timeline):
// Fade the vignette in over the first second
tl.fromTo("#hf-vignette",
{ "--vignette-color": "rgba(0, 0, 0, 0)" },
{ "--vignette-color": "rgba(0, 0, 0, 0.7)", duration: 1, ease: "power2.out" },
0,
);
// Or breathe the size in and out (works with any easing)
tl.to("#hf-vignette", { "--vignette-size": "35%", duration: 1, ease: "sine.inOut" }, 2);
