## 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.

## 2025-03-24 - Screen Reader Game Feedback
**Learning:** Static instructions inside `aria-live` regions force screen readers to unnecessarily repeat the static text every time the dynamic content updates.
**Action:** Extract static text into a separate sibling element or parent container and only apply `aria-live` to the specific node that dynamically updates. Always ensure visible keyboard instructions are provided for custom HTML5 game interfaces.
