docs: add inline documentation to all modified files

fix: use cu128 wheels matching ZeroGPU's torch CUDA 12.8 environment

fix: build diff_gaussian_rasterization from source for H200 (sm_90) GPUs

fix: add antialiasing param and handle 3-value return from rasterizer

fix: adapt gaussian renderer to standard diff_gaussian_rasterization API

Bump max_hole_size to 0.06 - middle ground between 0.04 (too weak) and 0.1 (too aggressive)

Dial back hole-filling: revert max_hole_size to 0.04, modest nbe increase with floor of 96, keep simplify connection

Improve hole-filling: higher thresholds, min nbe floor of 128, double-pass fill

Update gamma correction to 1.8

Fix float type error in sampler steps

Revert "Fix: Bypass C0 multiplication for DC-only SH - directly add 0.5 bias for correct shadow rendering"

Fix: Bypass C0 multiplication for DC-only SH - directly add 0.5 bias for correct shadow rendering

Fix: Change max_sh_degree to sh_degree for Python SH conversion

Fix: Apply proper DC bias fix - Enable Python SH conversion with +0.5 bias, remove masked boost patch

Revert: Remove all boosts and gamma correction - Restoring original behavior

Fix: Remove division by C0 (0.282) - SH boost amount is now RAW +0.5

Fix: Masked Constant Boost (+0.5) - Exact shadow color match, no variable curve

Fix: Restoration of Smart SH Boost (Threshold 0.4, Max 0.7) - Overwriting regression

Fix: Revert aggressive Hump boost, use Soft Boost for natural colors. Add Debug Image to UI.

Fix: Safe SH Boost - Hump curve to preserve True Black (0.0) while lifting shadows

Fix: Smart SH Boost - Only lift shadows (<0.4 lum), preserve highlights

Fix: Remove global gamma, bake BiRefNet model, optimize Docker for startup

Fix: Revert render hack, apply SH ambient boost to keep background black

Fix dark shadows in AR by lifting float values in render_utils.py

Fix: remove duplicate line

CORRECT: Texture gamma 2.2 ONLY, remove video gamma

Restore gamma 2.2 configuration

Restore to working version: texture gamma 2.2, remove video gamma

Fix opt mode gamma: 2.3 → 2.1 (consistency with fast mode)

Fix gamma values: video 2.2, texture 2.1, add GLB Raw export

Fine-tune gamma correction and fix video rendering brightness

Fix dark model issue with gamma correction (Linear → sRGB)
