==== Function Details ====
=== Parameter Breakdown ===
* `playerid`: Target player's UI instance
* `uiid`: Parent UI container ID
* `elementid`: Specific text element to modify
* `size`: Font size in points (recommended range: 8-72)

=== Usage Notes ===
1. Only affects text-based UI elements
2. Size values outside reasonable ranges may be clamped
3. Changes apply immediately to the specified player's UI
4. For responsive design, consider:
   - Calculating size based on screen resolution
   - Using relative sizing (e.g., percentages)

==== Best Practices ====
* Maintain readability:
  - Minimum suggested size: 12pt
  - Headings: 16-24pt
  - Body text: 12-14pt
* Test across different screen resolutions
* Combine with `setColor` for better visibility
