SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

The current Idavoll game UI often lacks mobile-first polish, determinism, and a clean vanilla-DOM baseline. This skill defines a process to redesign the UI shell, HUD, overlays, and menus to be consistent, on-system, and testable.

Core Features & Use Cases

  • Deterministic UI shell: vanilla DOM with a single source of truth for UI state, ensuring replayability and predictable rendering.
  • UI kit integration: strict usage of the Idavoll game UI kit tokens and patterns, with no off-system overrides.
  • Modular overlays: HUD, upgrades, menus, and results overlays designed as reusable components with clear interaction contracts.

Quick Start

Apply the UI kit to the Idavoll game and wrap the root in .idv-ui-theme to validate deterministic, mobile-first UI.

FAQPage Schema
How do I build a deterministic game UI using vanilla DOM?

A deterministic game UI uses vanilla DOM with a single source of truth for UI state, ensuring replayability and predictable rendering. It enforces strict UI kit primitives and root wrapping for consistent behavior.

Can I use React for my game HUD and overlays, or do I need vanilla DOM?

No, React is not allowed. This approach requires strict vanilla DOM usage with no React, enforcing UI kit primitives and a root wrapper to maintain determinism and mobile-first usability across the game UI shell.

What is the best way to ensure mobile-first polish for game menus and overlays?

The best way to ensure mobile-first polish is to design modular overlays, menus, and HUDs as reusable components with clear interaction contracts, wrapping the root in a unified UI theme for consistency.

How do I apply UI kit tokens to game UI components without off-system overrides?

Apply UI kit tokens by enforcing strict usage of the game UI kit patterns and primitives, ensuring no off-system overrides exist and wrapping the root element in the required theme class.

Why does my game UI lack replayability and consistent rendering across sessions?

Your game UI lacks replayability because it lacks a deterministic baseline. By using vanilla DOM with a single source of truth for UI state, you ensure predictable rendering across sessions.
