v0.3.1: Cyrillic paths, Base/Large downloads, point-cloud reveal, video autoplay

What's new in 0.3.1

Fixes

• Non-English / Cyrillic folder paths now work. If the app or your photo sat under a folder with non-Latin characters, it refused to load or crashed on the depth plane. Fixed.
• Switching the depth model no longer errors (the "ensure_downloaded" crash).
• Cleaner controls: Extra sharpness only shows under Boost, Amount greys out when Detail is Off, and Live preview turns off properly.
• "Find my files" now copies the whole Streamline set (sl.*.dll), a common cause of setups that would not hook.

New

• Base and Large depth models download on demand (verified fp16). Small still ships built in.
• Depth model choice moved to the main panel. Neural strengths now start at max, so the effect is obvious out of the box; dial down to taste.
• New point-cloud loading animation: your shot rebuilds as a 3D depth point cloud while it processes, then lands into the result. Also in the style-compare panes.
• Videos auto-play once loaded, so a loaded video shows motion instead of a black frame.
• New first-run intro showing real DLSS 5 off vs on.

Notes

• The Depth Contrast slider was removed. Testing showed it does not change a still image's output (DLSS only uses depth when there is motion). Depth is being put to work in video next.
• You still bring your own DLSS 5 files into dlss_files\. Nothing from NVIDIA ships with the app. If setup gives you trouble, use the required-files pack and follow the steps.
