MegaFractal 0.1.0 - quick start
====================================

1. (One-time) populate the formula cache. Many demo UPRs reference UF's
   bundled Standard.{ucl,ufm,uxf} plus public-DB formulas; this script
   copies the bundled Standard stubs and downloads ~77 public ones into
   UF_formulas/. Pick one:

       powershell -ExecutionPolicy Bypass -File scripts\fetch_formulas.ps1
       python scripts\fetch_formulas.py        (if you have Python)

2. CLI:

       mf.exe demos\basic_mb\basic_mb.upr out.png -sl 4

3. GUI:

       mf_gui.exe                                 (empty - use Browse...)
       mf_gui.exe demos\basic_mb\basic_mb.upr   (load directly)

Add `-device "NVIDIA GeForce RTX 4090"` (or your card's name) to pick a
specific GPU. List devices: `mf.exe -list-devices`.
