Video settings playground

A settings UI derived from rules, not hand-designed. Every setting is classified on a fixed set of facets, and one deterministic engine turns the PC's hardware and the player's choices into what the screen shows. Every page runs the same engine against six sample PCs.

• Facet explorerEvery setting as a collapsible tree, grouped by the facets you pick. The quickest way to understand the classification.
• Main menu mockupThe settings screen the rules produce, as a WinUI 3 app: hardware-aware choices, locked fields, a change ledger and Basic / Advanced / Expert detail levels.
• In-game mockupThe same rules applied to a running session: a live tuner over the game and a pause menu.
