/**
* @file ui/overlay/simple_settings_overlay.cpp
*
* @brief Curated user-facing settings overlay.
*
* Fullscreen, console-style settings screen: category rail on the left, a
* column of setting rows with left/right value steppers in the middle, a
* description panel on the right and a button legend along the bottom.
* Fully navigable with a controller (dpad/left stick, A/B/X/Y, LB/RB),
* keyboard (arrows/Enter/Esc/Q/E/R/F) and mouse.
