## 2025-03-23 - Game Key Scrolling
**Learning:** Browsers natively scroll the page when users press Space or Arrow keys. When building a web-based game, this creates a frustrating UX where the game viewport jumps around while playing.
**Action:** Always call `e.preventDefault()` on keydown events for typical game controls ("Space", "ArrowUp", etc.) when the focus is on a game container or the body.

## 2024-05-24 - Explicit Instructional Text for Custom Key Bindings
**Learning:** When building interactive HTML5 widgets or games with custom keyboard event bindings, users do not natively know the required inputs, leading to poor UX if instructions are missing.
**Action:** Always provide explicit, visible instructional text for custom keyboard interactions and use CSS `pointer-events: none` on overlays to ensure they do not block user interactions.
