// LIVE UI TUNER — paste into UnityExplorer's C# Console. Edit the knobs, Run, look,
// repeat. Nothing persists; relaunching reverts everything.
//
// IMPORTANT: run this IN-GAME (not the main menu). Different scenes have different
// canvases, and the overlapping text is in the gameplay HUD.
//
// scaleFactor = (screenW/refW)^(1-match) * (screenH/refH)^match
// match=1 scales by HEIGHT (logical height stays 1080 = the design height).
// Lowering match shrinks logical height below 1080 and CRAMPS things vertically.
