Block Widget Demo

This example demonstrates the versatile Block widget, which provides the visual container, borders, and titles for almost every other widget in ratatui_ruby.

Key Concepts

• Borders: Choose which sides to show and apply different border types (plain, rounded, double, thick, etc.).

• Titles: Add a main title with alignment or multiple titles at the top and bottom with independent styles and positions.

• Padding: Define inner spacing using uniform or directional (L/R/T/B) values.

• Styling: Individually style the block’s content area, its borders, and its titles.

• Custom Border Sets: Create entirely custom border appearances by defining each character in the border set.
