Mesh gradient support with tokens

Currently there is no way to make a tokenized mesh gradient with transparency.

👇 Sample code from a Claude mesh gradient maker, bound to Figma color variables. 

.mesh {
  background:
    radial-gradient(181.01% 100% at 0% 100%, var(--ramps-amethyst-08, #653FC6) 0%, rgba(101, 63, 198, 0.00) 100%),
    radial-gradient(99% 99% at 100% 0%, var(--ramps-info-06, #88AEE4) 0%, rgba(136, 174, 228, 0.00) 100%),
    var(--ramps-amethyst-02, #F0EBFF);
}

This is impossible in Figma due to the lake of transparency.

Once you use a tokenized color in a gradient, you completely lose the ability to make it transparent, without breaking it. Once you break it, light/dark modes no longer work.

Seems like it would be relatively simple to make a transparency dropdown next to the tokenized color.
