# HyprTile Film Lab

A multi-pass analog film-stock simulation for the HyprTile ScreenFX runtime host.

Pipeline:

1. quarter-resolution highlight extraction
2. horizontal dual optical blur
3. vertical dual optical blur
4. full-resolution film-stock synthesis

The RGB optical branch carries warm/red film-base halation while alpha carries
neutral diffusion. The final pass adds gate weave, stock colorimetry, toe and
shoulder response, dye-density behavior, split-toning, vignette and temporally
changing film grain.

The effect is intentionally continuous at 30 FPS so grain and gate weave remain
alive on an otherwise static desktop. Normal user-driven frames still render at
the compositor's regular cadence.
