## Summary by CodeRabbit
* **Style**
* Updated document title styling for improved readability (larger font,
increased line height, heavier weight).
* Refined spacing so titles align correctly when a document icon is
present (no extra top padding).
* Improved emoji rendering by using a consistent font and removing an
unnecessary visual artifact.
* Simplified title container behavior to ensure stable, predictable
alignment without placeholder-based shifts.
* **Chores**
* Minor UI cleanup and consistency adjustments for the icon/title area.
