Overlay requirements

Paragon Overlay depends on borderless windowed mode, a valid top-level Paragon section in your profile YAML, and a non-conflicting overlay hotkey.

Use borderless windowed mode.
Confirm your profile YAML includes a top-level Paragon section.
Check toggle_paragon_overlay (default F10) for conflicts.
