CC Environment now fades nearly transparent environment texels to black continuously (colour / max(alpha, 1e-3)) instead of a hard 1e-6 un-premultiply cut-off, which turned the filtered map's float noise into colour. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

//! GPU effects, Numbers and Timecode (kernel `ftx_text` in `shaders/fx_text.wgsl`). The text

//! the CPU effect's own coverage: fill and stroke ring), uploaded as one image and composited

//! on the GPU with the layer, Timecode's box and the fill / stroke colours.
