NUI accessibility and performance

The NUI lessons get an interface on screen. This one makes it good: it does not trap the player's mouse, it scales from 1080p to 1440p to ultrawide, it does not burn frames when idle, and people can actually read it. These are the details that separate a hobby UI from a sellable one.

You'll learn: Focus and input traps, resolution scaling, render cost, and readability, so your in-game UI is fast, scales across monitors, and stays usable, not just visible.
Time: ~20 minutes.
You need: A working NUI resource (the NUI lessons).

BEFORE YOU START

Make it good, not just visible

Release focus on every close path

The player is never stuck with a hidden UI holding focus.

Call SetNuiFocus(false, false) on every way the UI can close: button, escape key, and any server-driven close. Test closing it five different ways.
